As a switch, the transistor is normally in either cutoff (load is ...) or saturation (load
is ...).

BEJ is not forward
-biased

BCJ is reverse Biased

VCE =VCC

BEJ is forward
-biased.

IB is large enough to cause Ic reach its saturation

Ideally, VCE can be neglected

... biasing can cause distortion in the output signal

... is the process of increasing the power, voltage, or current by
electronic means and is one of the major properties of a transistor.

a BJT exhibits current gain

When a BJT is biased in the active (or linear) region, the BE junction has a low
resistance due to ... bias and the BC junction has a high resistance due to ...
bias.

The region along the load line including all points between saturation and cutoff is
known as the linear region of the transistor’s operation; the transistor is operated in
this region.

For example, the bias has established a low Q- point. As a result,
the signal is will be clipped because it is too close to ...

The point at which the load line intersects a characteristic curve represents the Q-point
for that particular value of IB.
