### Re: [HELP] Electronic schematic question

Thanks, but I knew about the potentiometer, what I don't understand is the arrow pointing toward it. Also, my friend said that some people already built this circuit and it worked so I guess it should work. The arrow represents the sliding contact in the pot. In this case the resistance between the...

### Re: Operational Amplifiers for use of noise canceling headphones

I can see a couple of potential problems. 1. Your are positioned such that the noise and inverted signal are not properly in phase so they do not cancel out. 2. You are amplifying the inverted noise signal too much or too little. 3. Connecting your desired signal source to the positive terminal does...
