Answer to Question #80088 in Electricity and Magnetism for DEVENDRA SINGH

Question

3. a) Explain the difference between analog bandwidth and digital bandwidth in
communication systems.

Answer 1

The analog bandwidth is the maximum sinusoidal frequency of the analog signal with which the circuit operates. It is related to the frequency at which the output will reduce its power by 1/2 of the maximum
The digital bandwidth of the circuit is smaller than the analog bandwidth, since the digital signals consist of values 1 and 0, and this is the square wave of signals. If we construct the frequency spectrum of a square wave, then the maximum content of the frequency in the signal is greater than the frequency of the square wave.
