In a PCM system, an input signal m₁ (t) = 8 cos(2000πt) volts. It is required to design a uniform quantizer with a maximum quantization error of 0.1 volts. 1) What is the minimum number of bits required to characterize the output levels? 2) What is the actual maximum quantization error if that minimum number of bits are fully utilized? 3) Assume a mid-rise quantizer is used. Assume also a sampling rate that is 50% above the Nyquist rate, with the first samples taken at t = 0 seconds. Sketch the quantizer output staircase waveform for one complete cycle of the input.
