Ex (3):- A signal that has the highest frequency component of 4.2MHZ and a peak to peak value of 4 volts is transmitted using a binary PCM. The number of quantization levels is 512 and P=0.04W calculate: 1. Code word length. 2. Bite rate.
For a PCM system, the value of the minimum transmission bandwidth is 25 kHz and the maximum frequency of the input waveform is 5 kHz. Estimate the total number of levels in the uniform quantizer present.
The output signal to noise ratio for a PCM system is minimum 40 dB. For sinusoidal full scale modulation, estimate the length of the codeword.
