Question

In compact disc (CD) audio technology, the signal is sampled at 44kHz. Each sample is represented by 16bits. What is the speed of the system in bits/second?

(a) 1.34 bits/second

(b) 2,750 bits/second

(c) 704,000 bits/second

(d) 1,441,792,000 bits/second

I have been asked this question in an online interview.

Question is taken from Signals in section Signals and Amplifiers of Electronic Devices & Circuits

Answer 1

Correct option is (c) 704,000 bits/second

The explanation is: 44000 X 16 = 704000 bits/s
