Questions about Q point-transistor

[QUOTE="rude man, post: 4989968, member: 350494"] You want a stable operating {"Q"} point so your signals are not distorted, the gain is optimized, etc. etc. There are many reasons the transistor current should vary only if the input signal(s) varies. Same goes for collector and emitter dc voltages. Beta of a transistor varies widely from transisitor to transistor and with temperature, to cite two prominent examples. Your circuit should not vary transistor c or e current as the base current varies. This means beta should be high as possible. This is like an op amp where the open-loop gain of the amplifier should not matter. [/QUOTE]
