Hello
I've been playing around a lot with common emitter amplifiers. I've just been making general signal amplification circuits. I use calculator tools to find the right biasing for any particular setup. At least, I think I'm biasing correctly (I'm probably not). But even if I decide to throw together know working circuits, I don't see much on how the input signal affects the Q point of a transistor, or what the best input voltage should be?
Understanding this will help me understand why different amplification stages are needed. Or what the true definition of a preamp is. What about an amplifier circuit makes it a preamp, or is it just the application it's used in?
Thank you!
