A transistor amplifier is shown in Fig. 21.27. The parameters of the

transistor are hie = 2 k, hoe = 25 S and hfe = 55, and the output load

resistor dissipates a signal power of 10 mW. Determine the power

gain of the stage and the input signal e.m.f. E. The reactances of the

capacitors may be neglected
