Extracted text: 1) Probability density function of quantization error for a "specially designed uniform quantizer" is given in Figure 1. Please calculate a) The value of A, if A is the step size b) Minimum and Maximum error introduced with this quantizer (error range) and Mean value of the quantization error c) Variance of the quantization error. Is this quantizer better or worse in terms of performance with respect to the uniform quantizer investigated in our lectures? Why, explain briefly pdf(e) A A/4 e -A/2 -A/4 0 A/4 A/2 Figure 1.
