The foremost function of a transistor is to do amplification (i.e., amplitude of a weak signal is amplified). Usually, a weak signal is given to the base circuit of a transistor and an amplified output is obtained at the collector. While doing amplification, care is to be taken that the shape of the signal must remain the same. This amplification of the signal without the change in its shape is known as faithful amplification.
In order to achieve faithful amplification, we have to provide some means by which the emitter-base junction is kept in forward-biased and the collector-base junction is kept in the reverse-biased condition during all parts of the signal. This is known as transistor biasing. In fact, to obtain faithful amplification, the quiescent (Q) point is set usually in the middle of the dc load line. To achieve this some means (circuitry) are provided known as transistor biasing.
