Four voice signals. each limited to 4 kHz and sampled at Nyquist rate are converted into binary PCM signal using 256 quantization levels. The bit transmission rate for the time-division multiplexed signal will be Correct Answer 256 kbps

Nyquist Rate 2 x 4k = 8 kHz Total sample 4 x 8 = 32 k sample/sec 256 = 28, so that 8 bits are required Bit Rate 32k x 8 = 256 kbps.

Assertion (A): Nyquist rate of sampling is the theoretical minimum sampling rate at which the signal can be sampled and still be reconstructed from its samples. Reason (R): When the Nyquist rate sampling is used, only an ideal low pass filter can be used to extract signal x(t) from sampled signal xs(t). Code:
