Hello Everyone
I am a junior year EE student working on a project for personal fun. I'm designing a circuit for a guitar effects pedal using PNP transistors and have a question about biasing them. The circuit I'm planning requires a specific ratio of Beta and I am wondering if it is possible to set the value of Beta somehow by biasing the transistors. Since Beta is ic/ib is it possible to set those values by choosing Rc and Rb to obtain the values of Beta that I want (within the range given on the data sheet). Or would I have to build a small circuit to measure ic and ib experimentally to find a transistor that has a value close to what I want?
PS my cheap multi meter can not measure HFE.
Thank you!
