Description[f,x] = errpdf(q) returns the probability density function f evaluated at the values in x. The vector x contains the uniformly distributed random quantization
Signal To Quantization Noise Ratio Formula
errors that arise from quantizing a signal by quantizer object q. f = errpdf(q,x) returns the probability density function f evaluated at the values in vector x. Note The results are not exact when the signal precision is close to the precision of the quantizer.Examplescollapse allCompute the PDF of the quantization errorOpen Script q = quantizer('nearest',[4 3]); [f,x] = errpdf(q); subplot(211) plot(x,f) title('Computed PDF of the quantization error definition quantization error.') The output plot shows the probability density function of the quantization error. Compare this result to a plot of the sample probability density function from a Monte Carlo experiment: r = realmax(q); u = 2*r*rand(10000,1)-r; % Original signal y = quantize(q,u); % Quantized signal e = y - u; % Error subplot(212) hist(e,20) gca.xlim = [min(x) max(x)]; title('Estimate of the PDF of the quantization error.')
