1. Review Questions 5.1 5.2 5.3 5.4 5.5 5.6 What is transmission? Distinguish among analog data,
analog signaling, and analog transmission Distinguish among digital data, digital signaling, and
digital transmission. What function does a modem perform? What function does a codec
perform? Identify the major reasons why digital transmission is preferred over analog transmis-
sion in business networks. Identify and briefly describe the three fundamental ways in which
digital data are encoded as analog signals. What is the meaning of "baud rate"? What is
amplitude-shift keying (ASK)? 5.7 5.8 5.9
Solution
5.1) transfering data from one place to anothe place or source to destination
5.2) analog data is a continuous data example speech signal
analog transmission is is transfering continuous signal
5.3) Digital data is a binary signal
5.4) modem function is modulator and demodulator
5.5) codec function is coder and decoder
5.6) noise is very less so the digital transmission is prefered
5.7) Baud rate: No.of bits transmitted per second. it is also called as data rate also.
Digital transmission is transmitting digital signals
5.4)
