Q1:

A data signal having frequency components from dc to 50 Hz is to be sent through pulse code modulation using an 8 digit code. The minimum carrier channel bandwidth is

A 1 kHz

B 2 kHz

C 4 kHz

D 8 kHz

ANS:C - 4 kHz

The Bandwidth should be half of the bitrate(Rb).

So, B.W = (8 * 100)/2 = 400hz.
It is the actual answer.
