Q2) A unipolar 14 bit ADC measures 0 – 8 volts full scale. a. What is the minimum resolvable voltage (or voltage resolution)? [Hint: resolution decrease as you increase the volts full scale] b. What is the percent quantization error? [Hint: percent quantization error for unipolar 10 bit ADC, 1 V full scale is: (resolution/max voltage) x100% or (975μV/1V) x100% = 0.0975%] c. What is the percent quantization error if a 1 volt max signal is input? [Hint: same resolution...

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...
