An Interesting FM/AM Detector Using An NE567

[TANAKASAN]

I was looking for a way to calculate NE567 Tone decoder values and I came across this interesting circuit:

OK, so it only works at 455 KHz but with one IC and eight other components you get a NBFM detector and a synchronous AM detector and no inductors required. Useful if board space is limited.

Very interesting:  I'll have to try it out.  Allows a simple switch between AM and FM
output for a receiver.
