A speech signal, band limited to 4kHz and peak voltage varying between + 5V and - 5V is sampled at the Nyquist rate. Each sample is quantized and represented by 8 bits. Assuming the signal to be uniformly distributed between its peak values, the signal to noise ratio at the quantizer output is-A-156 dBB-32 dBC-48 dBD-64 dB-C-48 dB

Question

APTITUDE CRACK · Accepted Answer

C 48 dB SNR = 6n + 1.7 = 6 x 8 + 1.7 = 48 + 1.7 .
