I want to test out two radio packet decoders I've built.
Can I just split the audio output, or do I need to amplify it or isolate the circuits? The decoders are the same hardware design (just changes in software), with the signal AC coupled via a small cap and then feeding a zero-crossing detector (PIC comparator).
