Rich,
There has never been an accepted broadcast transmission signal process that has had a minus 96 db noise floor. The stereo FM broadcast protocol used for the past several decades has been accepted as the “best so far” audio standard. With the advent of composite clippers, baseband processing and exciter and antenna design, the weak link will forever be the exciter.
I remember when the new silver bullet was the detection of AM modulation on the FM carrier, and the phase shifting control supplied by adjusting the output tuning and antenna tuning of the station. It reduced the weak signal noise at the receiver, thereby extending the listenable range of the signal.
And finally, even though HD-R FM out of the exciter will not reach Cd quality audio delivered to the receiver, the audio processing chain of most stations certainly will. That, of course, is ignoring the quality of the D/A and A/D converters required to allow the audio to be processed in the first place. I guess we haven’t reached perfection, yet. I still want to know where Buck Rogers went to.
