PROPER BIASING OF A TRANSISTOR - enables the transistor to be used as an
amplifier. To function in this capacity, the emitter-to-base junction of the
transistor is forward biased, while the base-to-collector junction is reverse
biased.
NPN TRANSISTOR OPERATION - basically is the action of a relatively small
emitter-base bias voltage controlling a relatively large emitter-to-collector
current.
PNP TRANSISTOR OPERATION - essentially the same as the NPN operation
except the majority current carriers are holes and the bias batteries are
reversed.
AMPLIFICATION - the process of increasing the strength of a signal.
AMPLIFIER - the device that provides amplification without appreciably altering
the original signal.
