transistor biasing is three type
1) voltage divider biasing
2)emitter biasing
3)base bias
4)collector bias
in genral we use the voltage divider biasing .
biasing is necessary for transistor work like
emmiter base junction is in forward bias & collector base in
reverse bias so that transistor works in active resion.
to fix the operating point at the middle of active region a
dc voltage is provided,ie it prevent the signal swing below
cut off.
Necesary of Biasing:
1)To fix the operating point at the middle of active region.
2)stabilize the collector current aganist temperature
varrions.
3)operating pont independant of transistor parameters
Q point of operating power is better.Q point of transistor
operating is very low distortion maximum signels or power
gain.Silicon for minium 0.7v germanium for minium 1v and it
is biasing of transistor.otherwords saturation point and
cutoff point works in the transistor is does not works the
amplifier

biasing is necessary for transistor work like
emmiter base junction is in forward bias & collector base
in reverse bias so that transistor works in active region
that is Q point (sufficient working og transistor)
The proper flow of zero signal collector current and maintainance of proper collector emitter voltage value during application of input signal.This process known as transistor biasing.
biasing is nothing but external energy applied across base
terminal to activate the transistor. it is neccessary
because to work transistor is properly. stabilisation is for
maintaining a q point stable.emitter resistance is for this
purpose.
