Hey all, I'm having a real hard time designing a simple on / off switch for an AC audio signal using an N-channel JFET. I've got some schematics (which I haven't breadboarded out yet), but in trying to simulate these ideas in Falstad, they never work. The circuit will run for a while and then quit, or occasionally i'll "reverse bias" the JFET, which also seems to be a big no-no in Falstad. Regardless of what I do I can never seem to get the AC signal to be affected.
Can anybody design a switch that works in Falstad... using a switch to control the gate voltage that will then cut off (pinch off?) the AC signal. It seems like that should be pretty easy, but I'll be darned if I can get anything to work. Lets say switch open, AC signal flows... switch closed, AC signal off.
thanks in advance.
