The effect of current shunt feedback in an amplifier is to

Crossover distortion behavior is characteristic of

The circuit shown, the figure supplies power to on 8 v speaker or L.S. The vaLUES OF $${I_C}$$ and $${V_{CE}}$$ for this ciruit will be

A power Amplifier delivers 50 W output at 50% efficiency. The ambient temperature is 25$$^\circ $$ C. if the maximum allowable junction temperature is 150 $$^\circ $$ C, then the maximum thermal resistance $${\theta _{Jc}}$$ that can be tolerated is

A class-A transformer coupled, transistor power Amplifier is required to deliver a power rating of the transistor should not be less than.

In a transistor push-pull Amplifier

A regulated power supply, shown in figure below, has an unregulated input (UR) of 15 volts and generates a regulated output V $$_{out.}$$ .Use the component values shown in the figure. The power dissipation across the transistor Q1 shown in the figure is

A regulated power supply, shown in figure below, has an unregulated input (UR) of 15 volts and generates a regulated output V o u t . out. .Use the component values shown in the figure. If the unregulated voltage increases by 20% the power dissipation across the transistor Q$$_1$$

In case of class A amplifiers, the ratio (efficiency of transformer coupled amplifier)/(efficiency of a transformer less amplifier ) is
