The bit rate for a signal, which has a sampling rate of `8 kHz` and where `32` quantization levels have been used is

Options

A. `32000 bits//sec`
B. `40000 bits//sec`
C. `64000 bits//sec`
D. `72000 bits//sec`

Answer

B

Explanation

No. of quantization levels `=2^(n)`
bit rate=sampling power `x` no. of bits per sample
