Sampling frequency of a compact disk is about ________(a) 30 KHz(b) 50

1.	Sampling frequency of a compact disk is about ________(a) 30 KHz(b) 50 KHz(c) 10 KHz(d) 70 KHzI had been asked this question by my college professor while I was bunking the class.This is a very interesting question from Costas Loop topic in section Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» The CORRECT choice is (C) 10 KHz The best EXPLANATION: Sampling FREQUENCY is the number of samples per second which helps in extracting a discrete-time signal from a continuous-time signal. For a CD, it is about 10 KHz.
