Q2. An analog signal x(t) = 4 sin (2nt) is ideally sampled, quantized, and encoded using a 3- bit PCM system. The sampling rate is 4 samples per second and the quantizer is of the uniform midrise type with a step-size of 1 volt. a) Determine the quantizer parameters and sketch its input/output characteristic. b) Sketch the waveform of the sampled signal for one complete cycle of the input. c) Sketch the waveform of the quantized signal for one complete cycle (4 samples). d) Sketch the resulting PCM wave for one complete cycle assuming that unipolar NRZ (on-off) signaling is used.
