You are given a signal x(t) with the following histogram (pdf)p_(x)(x).
(a) Find the 9 -level compandor quantizer, i.e., find numerical values for the 9 quantization levels
q_(1),q_(2),dots,q_(9)& the endpoints of the quantization segments, x_(1),x_(2),dots,x_(10).
(b) Is the compandor any different from the intuitive quantizer? Why?
(c) Compute the quantization error (numerical value) for your compandor in (a).
(d) Compute the quantization error associated with a 9-level uniform quantizer.
(e) Compute the quantization error associated with a 9 -level optimal quantizer.
(f) How would you rank the 3 quantizers? Why?
