|Biasing means ,the fixed current and fixed voltages are described for the transistor for its proper operation .the point at which fixed current and voltages are described is called Q-point.|

|It decides the mode of operation of the Transistor i.e either Amplifier or switch. It also decides the output voltage swing in case of amplifier circuit.|
|Suma said: (Aug 6, 2011)|
|Biasing means giving supply to the circuit.|
|Pankaj said: (Oct 19, 2011)|
|Biasing means when some external voltage is applied to a transistor and thus the process of forwarding and reversing continues.|
|Suzan Gardi said: (Jan 8, 2012)|
|Biasing means giving volt to the circuit.|
|Arjun said: (Jul 23, 2012)|
|Biasing is for to stabilize the Q-point at fixed location to produce our require output swing and the dc level for proper operation of the transister circuit.|
|Zeeshan said: (Jul 31, 2012)|
|The biasing need for transistor operation a proper q-point.|
|Wais Alam S/O Mr.S.Alam said: (Oct 30, 2012)|
|Biasing of transistor is employed to set the operating point in the middle of the active region of the transistor characteristics or stabilize the collector again temperature variation.|
|Jay Rathod said: (Nov 14, 2013)|
|Biasing decides the collector(output) voltage, current and Base current thus decides a steady Q-point.|

|Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor. A transistors steady state of operation depends a great deal on its base current, collector voltage, and collector current and therefore, if a transistor is to operate as a linear amplifier, it must be properly biased to have a suitable operating point.|

|Bias voltage typically refers to an electrical charge applied to the gate or base of a transistor or FET's. This applied voltage causes the component to become conductive, thereby passing electrical current through its collector and emitter stages.
The amount of current passed through the component is also directly related to the amount of bias voltage applied. Depending on the type of transistor, this voltage is either positive or negative and is referred to as a forward or reverse bias.
These voltages are, therefore, used to switch electronic components on or off, keep them active, or control the amount of current passing through them.
