Teaching TN TRB EC Mock Test Communication Systems Pulse Modulation Pulse Code Modulation (PCM) System
The Bandwidth of a TV video plus audio signal is 4.5 MHz. If this signal is converted into PCM bit stream with 1024 quantization levels, the bitrate of the resulting signal will be:
(Signal is sampled at a rate 10% above the Nyquist rate)1
99 M bits/second
2
108 M bits/second
3
100 M bits/second
4
98 M bits/second
