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. If the bits 0 and 1 are transmitted using bipolar pulses, the minimum bandwidth required for distortion free transmission is-A-64 kHzB-32 kHzC-8 kHzD-4 kHz-D-4 kHz

Question

APTITUDE CRACK · Accepted Answer

D 4 kHz According to Nyquist Criteria, minimum sampling frequency = 2 x 4 k = 8 kHz But each cycle can accommodate two bits Thus minimum frequency = 4 kHz.
