The classical approach is to heavily band-limit the input of an following hard-limiter. But would it possible to merge both functions in several stages of an IF-strip? I think most individuals cannot follow much of this idea but time-nuts have the same problem :-) My main interest is a

Hi Most communications systems also have constraints based on signals in adjacent channels. That pretty much forces a solution of lots of filter before lots of gain. Distributing both gain and filtering across multiple stages gets you into a variety of issues that map junk into the passband. Once
