The bit rate for a signal, which has a sampling rate of `8 kHz` and whare `16` quantisation levels have been used is

Options

A. 32000 bits/sec
B. 16000 bits/sec
C. 64000 bits/sec
D. 72000 bits/sec

Answer

a

Explanation

If n is the number of bits per sample, then number of quantisation level`=2^(n)`
Since the number of quantisation level is `16`
`implies 2^(n)=16impliesn=4`
`:.` bit rate = sampling rate x no. of bits sample
`=8000xx4=32,000 " bits"//"sec"`.
