Darn spell checker got the title wrong. Should be GND, not And.
As you can see from the title, I am mightily confused about the - (minus) side of things.
Here is the circuit that I am trying to build. In the circuit there are 3 references to 《》, the arrowhead symbol., or gnd.
So, in my simple way of thinking, can I wrap all 3 of those together ? Somehow that don't seem right. The negative of a 17v DC supply, one side of my audio signal, AC, and the common of the circuit. If the audio signal were not there I would feel comfortable wiring the other 2 together, but this is a puzzle. This seems like a basic understanding topic which I clearly lack, so could someone point me to a clear discussion or explanation of it ?
My next project has both a -- and a + 15v DC requirement. I bought a bench power supply that delivers Both, but I just know that I will be back here with lots of questions. Somehow the -- and ++ issue seems related to this thread which is why I put it here. Please ignore it if you think it belongs in a separate thread.
Thanks.
