Question

The noise power σn^2 can be reduced by increasing the sampling rate to spread the quantization noise power over a larger frequency band (-Fs/2, Fs/2).

(a) True

(b) False

I got this question by my school teacher while I was bunking the class.

I want to ask this question from Sample and Hold topic in portion Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Correct option is (a) True

To explain: The noise power σn^2 can be reduced by increasing the sampling rate to spread the quantization noise power over a larger frequency band (-Fs/2, Fs/2), and then shaping the noise power spectral density by means o f an appropriate filter.
