Conclusions and Recommendations (5 Marks)
This section (100 – 200 words) should briefly summarise the
main conclusions of the laboratory exercise. What comes first,
simulation or hardware construction? How simulation helped in
building and understanding the experiment? How can the results
be used in a real engineering context? Was the circuit stable?
How can the experiment be improved? What further research
would you undertake to further investigate the question if you
had the time and resources?

Module Learning Outcomes
1. Apply electric circuit analysis techniques.

8. 3. Design and construct digital or analogue circuits.
5. Explain the behaviour semiconductors.
6. Use computer aided simulation software to implement and
simulate electrical and digital circuits.
Part A: Semiconductor Devices, LO 5,6 [10 marks]
Using myDAQ device, you are required to build a hardware
circuit used to convert alternating voltage to pulsating direct
voltage using semiconductor diodes. This circuit is called half
wave rectifier. Figure 1 displays a similar circuit.
Figure 1: Half wave rectifier circuit
1. Build the circuit in Figure 1 (Small breadboard will be
provided) and present it to your tutor during your face-to-face
viva.
2. Choose the input frequency to be your last three digits of
your SID.
3. Insert clearly labelled screenshots of your hardware circuit
and produce a graph showing the voltage across the load
resistor.
4. Explain the produced graph and steps you followed to
accomplish it. This should prove your ownership of the design
and understanding of the functions of MyDaq kit.
5. Use the assignment template provided.
Part B: Digital Circuits LO 3,6 [75 marks]

9. You are required to design, simulate and construct a keypad
controlled decimal-to-BCD encoder connected to a common
anode seven segment LED display. The full circuit diagram of
the project is given in Figure 2 below.
Figure 2: Circuit diagram illustrating the use of an encoder and
a decoder to drive a 7-segment LED display via a 0-to-9 keypad
In addition, you will be required to produce a 1500 word
technical report based on the design, build and test.
As part of the assignment, you will be required to complete the
following tasks:
1. Draw and simulate the circuit diagram given above (Figure 2)
using NI Multisim.
· Save the file as yourSID_7segment and upload a copy of the
file to Moodle (Link will be provided by your Tutor).
· The file should be executable by your tutor.
·
2. Build Figure 2 neatly on the large breadboard using the
following components available in the lab:
· Nine push buttons,
· Nine 10kΩ resistors,
· One CD74HC147E integrated circuit (it is the CD74HC147 in
Figure 2),
· One SN74HC04N integrated circuit (containing the NOT
gates),
· One SN74LS47N integrated circuit (it is the SN7447A in
Figure 2),
· Seven 330Ω resistors,
· One common anode 7 segment display,
· Wires.
Use the components datasheets available on Moodle to
understand how to connect the components.

10. 3. Redesign and simulate using NI Multisim a BCD(binary
coded decimal) to sevensegment decoder IC to show your SID:
· The decoder should be able to drive the 7 segment to display
“0” when no button is pressed. If Push Button1 (PB1) is
pressed, the 7-segment displays your first ID digit and so on
from left to right as stated in table 1.

4. From the specification of the circuit:
· Determine the required number of inputs and outputs and

11. assign a symbol to each input and output.
· Derive a truth table that defines the relationship between the
inputs and the outputs.
· Using Karnaugh maps, derive a simplified Boolean function
for each of the input variables.
· Draw the logic diagram of the simplified circuit using
Multisim.
5. Replace the SN7447 IC in the Multisim file
(yourSID_7segment) with the simplified logic circuit you
designed in task 3 above and simulate the circuit. Save it as
yourSID_D7segment and upload a copy of the file to Moodle
(link is provided by your tutor).
6. In your report, discuss the steps you have followed to
accomplished tasks 1, 2, 3, 4 and 5 respectively (as specified
above). Include screenshots of the simulations and the design
process in your report.
7. You are required to present Part A and B to your tutor in a
form of oral assessment. Your tutor will be asking you question
that tests your depth of understanding on the taught subject.
Part C: AC circuits LO1, 6 [15 Marks]
The circuit in figure 3 shows a series resonant circuit.
Vin is 20 V r.m.s, choose the value of L1 to be the last non-zero
digit of your student ID (eg. If your student ID is 7256105, then
L1 =5mH).
Simulating the circuit in Figure 3 on Multisim.
i. Plot the frequency response of the circuit.

Guidance notes and considerations
You will be graded on the following aspects of the project:
· Implementation Part A and B
Your project will be assessed on how effective the concept was
implemented on hardware. The focus will be on the quality of
the work, the finished appearance and its performance during
the demonstration. You will be asked some questions on your
finalised hardware. You will be informed about the date by your
tutor.
· Design
You will be assessed on your ability to produce a simplified
design and correctly simulate the project using Multisim
software. Please refer to the assignment template.
· Finalreport
You will be assessed on the quality of the report of the system
designed and the simulation. A key feature will be how easily it
would be for someone else to understand, reproduce or modify
your project by following your report.
Always consider the following: What, when, why, where and

13. how in developing your assignments. These will assist you to
analyse, evaluate and reason your points of view. Remember to
support your concept / academic argument with an example as it
allows the reader to appreciate the rigour and your
understanding of the task.
Note that you will be marked also against your reflection and
critical analysis, knowledge and understanding, evidence of
reading, referencing & bibliography and presentation
&grammar& spelling.
Guideline for the report outline:
Make sure you follow the Assessment template on Moodle.

capped at 40% maximum.”
Plagiarism avoidance:
Recommended Referencing Practice - Citations and Quotations
In order to avoid submitting any sections which may contain
“plagiarism” or “poor academic practice” or “collusion” it is
important that students should adopt the following referencing
practice:
CITATIONS: Include an in-text citation (author and year of
publication) and give the correct reference at the end of the
work for any sources used or referred to or paraphrased in the
work but not directly quoted.
QUOTATIONS: Mark up any directly quoted text using
“quotation marks” (this enables Turnitin to identify “quoted”
sections), add an in-text reference (author, year of publication
and page number) and include the correctly formatted reference
at the end of the work;
Examples of “plagiarism” or “poor academic practice” or
“collusion”:a. Excessive and inappropriate use of quotations.
e.g. Where the assessment learning objectives require a student
to explain an argument but the student simply copies an
explanation from another source, correctly annotating the work
as a quotation.
b. Quoted sections that are not correctly annotated as quotations
(using quotation marks, which will allow Turnitin to identify

17. quoted sections), but where there is an attempt to cite and
reference the source.
e.g. If a student includes separate paragraphs in the format “In
2005 Smith found evidence that…” and then copies the rest of
the paragraph directly from the cited source.
c. Copying material from another source without indicating it is
a quotation (indicated by using quotation marks, which will
allow Turnitin to identify quoted sections).
d. Omitting from the reference list and/or bibliography at the
end of a submission any sources that a student has used to help
formulate their own answer, even if the actual submission is
written in the student’s own words.
e. The use of substantial sections of text that have been
previously written by others, but with no clear indication that
the text is not the student’s own work.
f. Copied sections of text from elsewhere without the source and
extent of the copied section being clearly indicated in the text
of the assignment.
g. Directly copied sections, such as several complete
paragraphs, without in-text acknowledgement of the sources
used.
h. Collusion e.g. two or more students with similar or identical
work, or with large sections of work that are similar or identical
in their individual submissions. This can apply to submissions
from students studying at the same or different institutions
regardless of the dates of submission.
