Hey. I want to test out a electrect microphone circuit soon. I understand that the standard electrect microphone produces very small voltage, so I understand that it needs an amplifier. Here's my schematic thus far based on the schematics I've read....
However, there are a few questions I have
1) Is it even necessary to have a cap at the end of the amplifier circuit? Why is it needed.
2) Most designs used inverting omp amps while my design uses non inverting. Is this wrong to do?
Thank you!
