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...

A piezoresistive accelerometer has a full scale of 100g with a full scale output of 100 mV. You have an 8-bit analog-to-digital conversion system with a full-scale input of 5VDC. You need to resolve the difference between a 5g and 10g acceleration, is this possible? Let’s assume that our A-to-D has the not just the ideal minimum quantization error but some additional noise, and say that we want to target an accuracy of +/- 1 least significant bit (LSB). How...
