If I have a working circuit, that I've tested an audio freqiencies with input from a frequency generator and output to an oscilloscope, how can I hook up a microphone as input, and/or a speaker on the output?
The background:
I've learned basic circuits, such as RC high/low pass filters, transistor amplifiers, oscillators, and simple linear ICs. I'd like to hook some of these up to audio equipment, but I'm a bit confused how to do this.
Let's say I have a filter... I'd like to take an audio via a microphone, pass it through my filter, and play it back via a speaker. I know that I can't just go and connect the wires directly - I need to know about the impedance of the microphone, preamping, the impedance of the speaker, matching transformers, etc. I haven't been able to find any guide about these - the few electronic texts I have don't discuss these very much. Can someone help me find a good guide for these?
Again, I don't need anything fancy. I'd like to know, given any circuit, how can I hook up a microphone to it, and how can I hook up a speaker to it.
