What is the biasing requirement of the junctions of a transistor for it's normal operation? And how these requirements are met in a common emiiter amplifier?

Biasing requirement.....

         For normal operation of a transistor,

(1) Emitter base junction is forward biased
(2) Collector bse junction is reserved biased.

For CE_ Amplifier

⚫ In common emiiter amplifier, input signalbis applied between between base and emitter ad output signal is taken across colletor and emitter.

⚫ Similarly, EB _junction i forward biased and CB _ junction reverse biased.
