I'm in the process of making colpitts oscillators as part of a theremin project. The question I have is this, why do most example circuits (bjt) have a low value emitter resistor in the range of 470r to 2.2k? Is it for stability, low drift, precision etc. or is it overkill.
I'm committed to 9v battery sound effect projects so low power drain is requisite.
