The transistor, like the diode, utilizes the property of the pn junction in a semiconductor. Unlike the diode, the transistor is a three-port device (with the three ports referred to as the base (b), collector (c), and emitter (e). The main functions of transistors are as switches and amplifiers. The common emitter amplifier increases amplitude of the voltage from an input signal. Since, there is input and output, there is also some gain (which is the ratio of the power going out to the power coming in: aim. The circuit of a simple dc bias circuit shown on the next page is constructed. All components are checked before they are used in the circuit. Vcc is input from of 12 v from the dc power supply. It has a turn on voltage of around.
