Transistor Biasing The circuit shown in Figure P2–84 is a typical biasing arrangement for a BJT-type transistor. The actual transistor for this problem can be modeled as 0.7-V battery in series with a 200-

kV resistor. Biasing allows signals that have both a positive and negative variation to be properly amplified by the transistor.

Select the two biasing resistors RA and RB so that 3 V 0.1 V appears across RB.AppendixLO1
