Biasing of transistor circuits is done for making it work in the desired region of operation.
Biasing means operationg the transistors in a particular region it could be either active(linear),cuttoff(off swith),saturation(nonlinear)For BJT*active region it acts as an amplifier EB jn is FB and ...
Basically transister contains active region, saturation, cut off region. In saturation and cutt of region transister is used as a switch. To use transister as amplifier the operating point should...

Answered On : Sep 11th, 2007Combinational circuit are those whose output depends only upon the present inputs but in sequential circuit the output depends upon both present and past inputs. that is the difference.
A sequential circuit uses flip flops. Unlike combinational logic, sequential circuits have state, which means basically, sequential circuits have memory. The main difference between sequential circuit...
Combinational Logic: Output are obtained as soon as inputs are provided. Output is independant of previous OUTPUT states.

Answered On : Jul 6th, 2006Biasing means applying the DC voltage across the device for its correct operation.
Biasing in electronics is the method of establishing predetermined voltages or currents at various points of an electronic circuit for the purpose of establishing proper operating conditions in electronic components.
Biasing is done for the linear operation of the device, since transistors give exponential response to the signal there exists a region where transistor gives near linear amplification of the input signal.
