-
Assertion (A): The duty cycle of a class C amplifier affects the power dissipation of transistor
Reason (R): At higher harmonics the efficiency of a class C amplifier becomes poor
-
If the op-amp in figure has a unity gain frequency of 1 MHz, the cut off frequency is
-
In a self bias circuit for CE amplifier the collector supply voltage is made twice. The collector current will
-
In a full wave voltage doubler circuit, the input frequency is 560 Hz. The ripple frequency is
-
Assertion (A): A tuned amplifier uses a parallel tuned circuit
Reason (R): A tuned amplifier is used to amplify a narrowband frequencies
-
The ac collector current is nearly equal to
-
From a measurement of the rise time of the output pulse of an amplifier whose input is a small amplitude square wave, one can estimate the following parameter of the amplifier
-
In an amplifier, if the output current flows for 120° of the input cycle, the class of amplifier will be
-
Assertion (A): If we overdrive an amplifier the output signal may get clipped
Reason (R): To dissipate heat to atmosphere a heat sink is sometimes attached to the case of transistor
