Answer:

Ans: (a) Source: CoolInterview.com

Ans: 9b). the voice signals have a bandwidth of 4Khz (300hz-3400hz signal bandwidth + 450*2hz guard bands= 4000hz) according to Nyquist criteria, the sampling rate must be at least double of this total bandwith. thus sampling rate= 2*4Khz = 8Khz. this is the reuired sampling rateto avoid loss of voice signals in transmission.

The frequency or pitch of female is 3600 hz and that of male is 3400 hz.There is a guard band of 400-600 hz needed to over come the ISI and Crosstalk so it is consider to be the 4k hz and according to the Nyquist criteria, the sampling rate must be at least double of this total bandwith.So it becomes 4*2k hz i.e. 8k hz for the noiseless transmission of voice signals.
