Show that, with a non-uniform quantizer, the mean-square value Show that, with a non-uniform quantizer, the mean-square value of the quantization error is approximately equal to (1/12) Si ?2i pi, where ?i is the ith step size and pi is the probability that the input signal amplitude lies within the ith interval. Assume that the […]
Show that the power spectral density of a CAP signal with a Show that the power spectral density of a CAP signal with a total of L amplitude levels is defined by S(f) = s2A/T |P(f)|2 where |P(f)| is the magnitude spectrum of the pass band in phase pulse p(t); the s2A is the variance […]
