If the analog signal to be quantized is a sinusoidal waveform, that is, x(1) = 9.5sin(2,000 m1) and if the bipolar quantizer uses 6 bits, determine a. the number of quantization levels; b. the quantization step size or resolution, A, assuming the signal range is from - 10 to 10 volts; c. the signal power to quantization noise power ratio.
