A MATLAB + SIMULINK test bench to simulate and analyse Sigma Delta modulators. Matlab script utilises Richard Schriers Sigma Delta Toolbox and Simulink models receives modulator coefficients from the toolbox and performs various simulations.
in every file of toolbox i'm getting this error: Matrix dimentions must agree:
spec = fft(V.*hann(NFFT))/(NFFT*(nLev-1)/4);
when i checked sizes of individual term i got this:
i'm not getting why dot multiplication is been used? for getting 1D FFT transpose of 1st term should have been taken. Any help would be appreciated. Thanks in advance
