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...

Two types of digital-to-analog modulation techniques are Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK). In ASK, two different amplitudes, and only two, represent the digital information. In FSK, only two different frequencies are used to represent the digital data. The Goal The goal of the design project is to design a Commsim circuit that will generate the following analog carrier based on a digital input stream: Output 2 0 -1 -2...
