1.	Which of the following amplifier is designed to operate in digital pulses?(a) Class D(b) Class C(c) Class AB(d) Class BThe question was posed to me in an interview for internship.My question is from Comparison of Amplifier Classes in section Power Amplifier of Analog Circuits
Answer» The correct choice is (a) Class D The EXPLANATION: Class D amplifiers USE a form of PWM to control the OUTPUT devices. Conduction ANGLE varies with the pulse width and doesn’t depend on the INPUT directly. The analog signal is converted into a stream of pulses representing the signal using a modulation technique.
