Hi, I am simulating a sigma delta modulator in spectre. I have chosen
fs=60kHz, fin=205 Hz, so that OSR is approximately 150 and so that coherent sampling condition is satisfied for N=2048, nper=7 (2OSR=N/nper).
I have run a tran simulation of 34.2 ms ( equal to nper periods) and I would like to post-process it in matlab for calculating the SNR through FFT.
The problem is that I have set the transient step = 0.2 us and I have a huge amount of output points (382000) describing the output bit stream.
How can I process them?
Thx,
Francis
