Explain Why it is necessary to bias a transistor, when used as an amplifier?
The input signal is usually given to the base of a transistor.
If the transistor is not biased, the Base,Emitter Junction will conduct only when the signal voltage is greater than 0.7V
When the signal is less than 0.7V the Base Emitter Junction does not conduct and therefore,the output taken at the collector will Zero.
This will result in a distorted output.
