Rf filter audio recorder (Techniek Radio/TV)

Nou ja, hij doet het ook zonder opnemen. Dus input > output en een paar transistors verder.

Dus die occilator waar ik wel aan dacht is niet in het geding.
Het zal niet eenvoudig zijn om een detectie van zo'n hoge frequentie te vinden.
Harmonischen kunnen vreemde dingen doen.

In het Dolby systeem zit overigens ook een afstemspoel. (wisfrequentie)
Maar ook die kan het niet zijn want die kun je eenvoudig uitschakelen.
