Binary data is to be transmitted using M-ary PAM over the ideal bandlimited passband channel with a bandwidth of B- 4 kHz. We use Raised Cosine (RC) pulses with roll- off factor γ 0.5 so that there is no ISI. If we want to achive a bit rate of 56 kbps, determine the required size of the signal set M, and the symbol rate.

Assume that an analog audio voice-frequency (VF) telephone signal m(t) occupies a band from 300 Hz to 3000 Hz. The signal is to be converted to a PCM signal for transmission over a digital telephone system. The signal is sampled at a rate 33.3% higher than the Nyquist rate. The maximum acceptable quantizatiorn error is 2% of the peak amplitude of m(t). The quantized samples are binary coded. Find the minimum bandwidth B of a noiseless channel required to transmit...

Q1 Marks: 40 A digital communication system has 96 analog telephone signals, each band limited to 4 kHz. The telephone signals are converted to digital binary data using Pulse Code Modulator (PCM) system, which use a uniform quantiser followed by an 8-bit encoder. The system uses two bits for synchronization. The digital binary data are then time-division multiplexed and transmitted over a single communication channel. Analyse the communication system by considering the following principles: (i) Determine the number of quantization...
