Q$1.$ A TV video and audio signal has a bandwidth of $6\mathrm{.}5MHz.$ The signal is sampled, quantized, and binary coded to obtain a pulse code modulated $($PCM$)$ signal. The signal is sampled at the Nyquist Rate.

a$)1)$ Calculate the Nyquist rate?

Wyquist rate $=2F_{\text{m}\text{a}\text{x}}$

$=2(6\mathrm{.}5{10}^6)=13{10}^6$

s$)$ If the sample are to be encoded into $512$ quantization levels, what is the number of binary pulses $($bits$)$ required to encode each sample?

What is the maximum error $($in percentage of $V_{PP})$ that is produced by this quantization?

Determine the number of bits$/$sec generated by PCM system of the binarycoded signal?

Derive the memory required to store a $7$ minutes passage of TV video and audio.
