%% Computational Cost of a Sample Rate Converter % Create |src|, a multistage sample rate converter with default values. % |src| combines three filter stages to convert from 192 kHz to 44.1 kHz. % Determine its computational cost: the number of coefficients, the number % of states, the number of multiplications per unit sample, and the number % of additions per unit sample. % Copyright 2015 The MathWorks, Inc. src = dsp.SampleRateConverter; cst = cost(src) %% % Repeat the computation allowing a tolerance of 10% in the output sample % rate. src.OutputRateTolerance = 0.1; ctl = cost(src)
