(choose chapter or problem)

A 2-V-peak sinewave signal is converted to digital form by a 12-bit ADC that has been designed to accept signals ranging from 5 V to +5 V. (In other words, codewords are assigned for equal increments of amplitude for amplitudes between 5 V and +5 V.) Practice Test 465 a. Determine the width of each quantization zone. b. Determine the rms value of the quantization noise and the power that the quantization noise would deliver to a resistance R. c. Determine the power that the 2-V sinewave signal would deliver to a resistance R. d. Divide the signal power found in part (c) by the noise power determined in part (b). This ratio is called the signalto-noise ratio (SNR). Express the SNR in decibels, using the formula SNRdB = 10 log(Psignal/Pnoise).
