The Basic function of transistor is to do amplification.
The weak signal is given to the base of the transistor and amplified signal is obtained at the collector. One important requirement during amplification is that there should be no change in the shape of signal.
This increase in magnitude of signal without change in the shape of signal is known as faithful amplification.
In order to achieve this, base-emitter junction of the transistor remains forward biased and collector-base junction remains reversed biased during all parts of the signal. This is known as transistor biasing.
"Proper flow of zero signal collector current and the maintenance of proper collector-emitter voltage during the passage of signal is known as transistor biasing"
A transistor amplifier must satisfy three basic conditions.
1) proper zero signal collector current
2) proper base emitter voltage at any instant
3) proper collector-emitter voltage at any instant.
