    The FFT calculation for asynchronous ADC

    Hi All; If we have an asynchronous ADC, therefore the sampling frequency is not constant. I don't know about calculation of FFT in this structure. Could you help me? Regards

    FFT calculation of Delta Sigma modulators

    Re: FFT calculation I don’t understand sigma delta in detail because I work in another field. But from there I wanted to test an idea for sigma delta and saw that is feasible or not (by matlab simulink). My problem is in fft calculation because the output of sigma delta modulator is different...

    FFT calculation of Delta Sigma modulators

    fft calculation Hi all; i have designed two sigma delta modulators one that has a 1bit quantizer and other has a 5bit quantizer, without the design of output filters how can i calculate the FFT of the output of each modulators for achieving power spectral density? Regards
