Exactly what I was thinking about. AFAIK the squelch block has an option 
to output either zeros or nothing when squelched.

I would not call it multiplexer, as this implicates for me interleaving 
of more than one stream to of from. I think our searched-fore behaviour 
is rather a selector or multiswitch.
