Hi folks,
I have been working/ building some oscillators recently in efforts to learn more about signals in general. I am wondering about the phenomena of mixed signals and how they influence each other.
I've just read the article on this site in mixed signals and it was quite informative on when such signals are undesirable, but I'm more interested now in those that are desirable. For example, I am looking at an electret mic input to an audio transistor base, an AC signal. The base I'd also biased by a voltage divider circuit at the same point. Are both signals on the same wire at the same time and while serving two totally different purposes, do they affect each other? I could see the D.C. In general increasing the amplitude of the AC waveform, but is there more to consider?
As always, thanks for any insights.
