In a CE amplifier it is desired that the signal should be able to swing equally in both directions. Then the Q point should be
-
In a base driver amplifier the voltage gain is the ratio of
-
Assertion (A): A class C amplifier is a timed amplifier which needs a tank circuit as the load in the collector circuit of the transistor for its proper operation
Reason (R): In class C operation collector current flows for less than 180° of the ac cycle and thus flows in pulses
