1. HISTORICAL BACKGROUND
ahir Dar University is found in Bahir Dar Town, the capital of the Amhara National
Regional State. The area within which Bahir Dar is situated is endowed with immense
scenic beauty and outstanding natural and cultural wealth. The immense natural
beauty and outstanding cultural and natural resources of the area have contributed to the
emergence of the town of Bahir Dar as the political center of the region. Today Bahir Dar is
one of the fastest growing towns in the country.
The establishment of Bahir Dar University owes a lot to two former higher institutions. The
Bahir Dar polytechnic Institute, which formed one of the faculties of the University, was
established in 1963 under the technical cooperation between the then Government of USSR
and the Imperial Government of Ethiopia. The objective of the institute was to train skilled
technicians in the fields of Electrical Technology, Agro- Mechanics, Industrial chemistry and
Metal, Textile and wood Technologies. The institute had to undergo number of program
changes within the area of technology until the commencement of the Engineering degree
program in 1996. Throughout these program changes, the institute did all what it could to
supply the labor market with the best technicians who are now running most of the
businesses in the industrial, educational, agricultural and other sectors.
The other fraternal institution of higher learning called Bahir Dar Teachers College was
established more than three decades ago. The two fraternal institutions of higher learning
were integrated and formed Bahir Dar University following the Council of Ministers
regulation no. 60/1999. The University was inaugurated on May 6, 2000 having the
following vision and mission.

1.3 RATIONALE
The objective of Electrical and Computer Engineering Education up to now was to educate trainable,
broad based Electrical, Communication and Computer engineers who can fit in the different
applications areas of Electrical engineering after given on job training for about a year. This has been
realized through the under-graduate curriculum both earlier and in the new revised curriculum.
The undergraduate program of Electrical and Computer Engineering Department produces Electrical
and Computer engineers who have broad knowledge through its five year programs. This training
gives the students such a broad background that they can fit in different sections of engineering field
such as power generation and transmission, communication, instrumentation, computer system and
networks installation and maintenance etc.
But with the rapid development of power and communication sector and the expansion of both public
and private engineering institutions in the country, deeper knowledge of various branches of
Electrical and Computer engineering is required along with other disciplines to play a leading role in
the technological development of a country. Therefore, as a step towards meeting this demand, the
Department of Electrical and Computer Engineering would like to elevate the level of training to
M.Sc to produce required Electrical and Computer engineers in the field of power, communication,
and control and instrumentation engineering who will have specialized knowledge in these fields.
The requirement for engineers who can engage themselves in academic and industrial sector in fields
such as research, development and engineering administration is also being felt. But currently the
graduate programs in Electrical and Computer engineering are being offered only at Addis Ababa
University. As of now the undergraduate programs in Electrical and Computer engineering is offered
at the following Ethiopian universities.

  • 4. BAHIR DAR UNIVERSITY ENGINEERING FACULTY Department of Electrical and Computer Engineering 4 1. HISTORICAL BACKGROUND ahir Dar University is found in Bahir Dar Town, the capital of the Amhara National Regional State. The area within which Bahir Dar is situated is endowed with immense scenic beauty and outstanding natural and cultural wealth. The immense natural beauty and outstanding cultural and natural resources of the area have contributed to the emergence of the town of Bahir Dar as the political center of the region. Today Bahir Dar is one of the fastest growing towns in the country. The establishment of Bahir Dar University owes a lot to two former higher institutions. The Bahir Dar polytechnic Institute, which formed one of the faculties of the University, was established in 1963 under the technical cooperation between the then Government of USSR and the Imperial Government of Ethiopia. The objective of the institute was to train skilled technicians in the fields of Electrical Technology, Agro- Mechanics, Industrial chemistry and Metal, Textile and wood Technologies. The institute had to undergo number of program changes within the area of technology until the commencement of the Engineering degree program in 1996. Throughout these program changes, the institute did all what it could to supply the labor market with the best technicians who are now running most of the businesses in the industrial, educational, agricultural and other sectors. The other fraternal institution of higher learning called Bahir Dar Teachers College was established more than three decades ago. The two fraternal institutions of higher learning were integrated and formed Bahir Dar University following the Council of Ministers regulation no. 60/1999. The University was inaugurated on May 6, 2000 having the following vision and mission. B

Mission of the University Based on the stated vision, Bahir Dar University has chosen the following mission: • The university wants to provide community oriented, practical education and carry out problem solving research and consultancy services • The university wants to give students the opportunity to develop creativity, critical thinking and a problem solving ability and become responsible • The university wants to produce responsible, creative and knowledgeable professionals who are ready to apply their theoretical and practical knowledge to match the needs of the society • The university wants to be recognized in effectively and efficiently utilizing its resources and modern information technology Considering the stated vision and mission in its establishment, the polytechnic Institute and Bahir Dar Teachers College, were renamed Faculty of Engineering and Faculty of Education, respectively. Currently the Faculty of Engineering comprises nine departments, Electrical and Computer Engineering Department is among the one. The Electrical and Computer Engineering department is one of the departments established by the former USSR in 1963. In 1996 the department launched the degree program. The department graduated more than 1000 graduates with B.Sc. degree. The department has gained the necessary experience to offer higher level engineering training program over these 10 years and it is the right time to upgrade the Department to a Graduate program offering status.
  • 6. BAHIR DAR UNIVERSITY ENGINEERING FACULTY Department of Electrical and Computer Engineering 6 As per the standard norms of any university, a Department which has completed 10 years of successful completion of offering undergraduate programs will be eligible to get upgraded to a Graduate programs offering status. Also, as of recent years, the academic and industrial community has expressed the requirement of graduate of different specializations in Electrical and communication Engineering with innovative skills to take part in the country’s academic, economic and industrial development. It is believed that this new graduate programs will address the acute shortage of higher level academic staff and higher level engineering administrative staffs. 1.1 Vision of the Department • To produce the best and most motivated students to serve the nation and the world. • To attract research funds based on advanced technical goals with high impact. • To develop lasting partnerships with industrial and governmental agencies. • To achieve visibility by active participation in conferences and technical and community activities. • To published enduring scientific articles and books • To earn prestigious awards and recognitions. 1.2 Mission of the department • To teach the fundamental of modern electrical and computer engineering. • To conduct and foster creative research by addressing the needs of industry, government and the scientific community. • To graduate well-balanced students with up-to-date technical knowledge, and high aspiration to excellence, poverty alleviation and leadership. • To publicize our achievement through enduring publications and via conference participation.
  • 7. BAHIR DAR UNIVERSITY ENGINEERING FACULTY Department of Electrical and Computer Engineering 7 1.3 RATIONALE The objective of Electrical and Computer Engineering Education up to now was to educate trainable, broad based Electrical, Communication and Computer engineers who can fit in the different applications areas of Electrical engineering after given on job training for about a year. This has been realized through the under-graduate curriculum both earlier and in the new revised curriculum. The undergraduate program of Electrical and Computer Engineering Department produces Electrical and Computer engineers who have broad knowledge through its five year programs. This training gives the students such a broad background that they can fit in different sections of engineering field such as power generation and transmission, communication, instrumentation, computer system and networks installation and maintenance etc. But with the rapid development of power and communication sector and the expansion of both public and private engineering institutions in the country, deeper knowledge of various branches of Electrical and Computer engineering is required along with other disciplines to play a leading role in the technological development of a country. Therefore, as a step towards meeting this demand, the Department of Electrical and Computer Engineering would like to elevate the level of training to M.Sc to produce required Electrical and Computer engineers in the field of power, communication, and control and instrumentation engineering who will have specialized knowledge in these fields. The requirement for engineers who can engage themselves in academic and industrial sector in fields such as research, development and engineering administration is also being felt. But currently the graduate programs in Electrical and Computer engineering are being offered only at Addis Ababa University. As of now the undergraduate programs in Electrical and Computer engineering is offered at the following Ethiopian universities.
