Example: In the chapter on BJT amplifiers, a worked example often shows calculating the quiescent point (IC, VCE) using a voltage-divider bias, then deriving the small-signal parameters (gm, rπ), and finally computing voltage gain, input and output impedances for a common-emitter stage with emitter degeneration.
