[Multi Select Question]

An analog signal is quantized & Transmitted using PCM. The maximum tolerable quantization error in sample amplitude is 5% of peak to peak value of message signal. The minimum numbers of bits required to encode each sample is

An analog signal is band limited to 4KHz and had its amplitude varying from -10 to10 V. It is then transmitted through a channel using a PCM system. The sampling rate is 50% higher than the Nyquist Rate. It is also given that the minimum bandwidth is 30KHz. Calculate the step size.

If a periodic signal

x(t) = 2sin 2π f₁t + Sin 2π f₂t + 6sin 2π f₃t

is PCM and encoded by a 4 bit encoder. Find signal to noise ratio (SNR in dB).

A binary channel with capacity 36 K bits/sec is available, for PCM voice transmission. If signal is band limited to 3.2 KHz then, the appropriate values of quantizing level and the sampling frequency will be –

The Bandwidth of the input to binary PCM is restricted to 4 kHz. The input signal varies from –3.4 V to 3 .4 V and has the average power of, the required signal to quantization noise power ratio is 20 dB . Assume uniform quantization, and then the number of bits required per sample is
