Hi all :
I am studing of delta sigma . and I have a question about the SQNR as function of input amplitude.
My question is " Can SQNR remain high when the input signal above 0dBFS ( such as 0.5dBFS) ?" I usually think that
that when the input signal approach the full scale, the modulator will unstable and the SQNR will decrease sharply,
but recently I see an article , its SQNR remain high as the input signal at 0.5dBFS, the result confuss me. Can
anybody tell me why . and I want to know that the input full scale indicate what ? Is full scale mean reference
voltage?
thanks!
