I'm designing a 2-1 MASH sigma-delta modulator. The structure is shown in Q1.jpg.
I run simulation in Hspice and grab the data from lis file.
Now, Y1 and Y2 I have already done well which their matrix size of 8192*1.
Error cancellation filters is shown in Q2.gif.
I don't know how to simuluate SNR of y from two given Y1 and Y2.
Plz tell me how to do.
