Sound card as digital Oscope
Biggest problem with this is that the sound card is filtered to audio band only. And for testing audio circuits, I'd want an Oscope that goes to at least 60KHz, 1MHz better. Why? Because: 1. The

Re: home-made signal generator question
My 2 cents: ICL 8038 or MAX038. The ICL 8038 is discontinued, but last I checked Mouser still has a few. The MAX038 is a bit more expensive but as I recall takes less external circuitry. And goes up

Re: home-made signal generator question
Hi Murat.. Not sure what you wanna use the signal generator for , but I used mine to fix audio equipment.. I downloaded a program from the NET which uses my sound card. I was able to change freq and

Re: Triac instead of relay ?
I said several times now the red waveform is NOT something you will see on a scope. It is what you get if you look at the furier analysis of the current. Basically you can describe any periodic signal

Re: signal oscillation
Where do you see a schematic or know the value of the feedback resistor? 2M feedback is really high, try to stay between 1k and 100k. maybe lower if you don't load the output with it (e.g.

Re: signal oscillation
The high-valued feedback resistor is perhaps causing a lot of phase shift because of the feedback capacitance, etc. Try a 6.8 pF capacitor across your 2M feedback resistor. Best, Scotty
