Question
The bit rate for a signal, which has a sampling rate of 8 kHz and where 16 quantisation levels have been used is
Answer: Option A
:
A
If n is the number of bits per sample, then number of quantisation level = 2n
Since the number of quantisation level is 16
⇒2n=16⇒ n = 4
∴ bit rate = sampling rate × no.of bits per sample
= 8000 × 4 = 32,000 bits/sec
