How can I measure snr from sigma delta adc and decimation after that but not to predict the snr ?
In frequency domain low pass filter has perfect magnitude spectrum but I can't get the perfect mmse snr?I have already considered the delay on it.
If anyone has opoins plz tell me,thx.
Did you mean to calculate the in-band noise and in-band signal power?How can we consider which frequency bin as in-band signal and in-band noise?Should I take the delay of the signal into consideration? Thx a lot...
Did it measure the snr in the same way for the decimation?
And what did it to be called in official?
Code:

Did it calculate the SNR in the same way in decimation?
Because I got 93db in sigma_delta modulation,it only retain 67 db after comb decimation?I use the example of oversampling rate=256,single bit;
thank a lot.
