A transistor amplifier stage comprises a transistor of parameters
hie = 800 Ω, hfe = 50 and hoe = 20 μS, and bias components and coupling
capacitors of negligible effect. The input signal consists of an e.m.f.
of 60 mV from a source of internal resistance 2.2 kΩ, and the total
load on the stage output is 4 kΩ. Determine the current, voltage and
power gains of the amplifier stage.
