Hello, you should try our circuit simulator...
for this kind of mixing you must use logic otherwise you will probably burn your components...
you should use a AND gate... so it will sum one signal or the other,..
however there are dozens of ways of doing it..
check the circuit simulator.. you will learn a lot in few minutes...
also google mixing logic signals
after the mixing you must use a mosfet driver like ir4427 to be able to drive them satisfactory
Bro I have some questions so I can learn from you.
- Dave Lawton didn't use a mosfet driver, only 555 signal output. His setup works in the circuit simulator. Moreover the 3524 ic has stronger current output. Then why do I need IR4427 or other mosfet drivers? I do not know.
- Thanks for hinting about those logic components. Truth be told I haven't studied them, so far. But I will.
- Circuit Simulator (by Falstadt, same on right?) it only shows output up to 300 hz then it does not show frequency. Or may be mine is an old version. I thought it was discontinued. So there are two options I think. Use SPICE or Proteus to simulate accurately. Or build a signal generator part of the circuit and check it on oscilloscope.
