Title: CALCULATING SNR OF DELTA SIGMA
Post by mavericks on Apr 19^th, 2011, 10:26pm

hi friends
i have designed a behavioural model of delta sigma using LTSPICE ..but i am not getting how to calculate FFT and SNR of the output data in matlab...!
my simulation parameters are

Fs=2.56MHz
Fb=5K
resolution =16bit
Q levels =1 bit
2 order mod
osr=256

so please if somebody have sample program and calculation values then will you please send on ashutosh_mec09@nitc.ac.in
