VIDEO AND RF AMPLIFIERS LEARNING OBJECTIVES Upon completion of this chapter, you will be able to: Define the term "bandwidth of an amplifier." Determine the upper and lower frequency limits of an amplifier from a frequency-response curve. List the factors that limit Frequency response in an amplifier. List two techniques used to increase the high-Frequency […]

Electronic Components
Amplifier feedback , positive feedback ,push-pull amplifiers ,summary of amplifiers and answers to questions q1. Through q33.
AMPLIFIER FEEDBACK Perhaps you have been around a public address system when a squeal or high-pitched noise has come from the speaker. Someone will turn down the volume and the noise will stop. That noise is an indication that the amplifier (at least one stage of amplification) has begun oscillating. Oscillation is covered in detail […]

Amplifiers : learning objectives , classification of amplifiers , amplifier coupling and impedance considerations for amplifiers
AMPLIFIERS LEARNING OBJECTIVES Learning objectives are stated at the beginning of each chapter. These learning objectives serve as a preview of the information you are expected to learn in the chapter. The comprehensive check questions are based on the objectives. By successfully completing the OCC/ECC, you indicate that you have met the objectives and have […]

Series voltage regulator , current regulators and voltage multipliers
Series voltage regulator The schematic for a typical series voltage regulator is shown in figure 4-34. Notice that this regulator has a transistor (Q1) in the place of the variable resistor found in figure 4-32. Because the total load current passes through this transistor, it is sometimes called a "pass transistor." Other components which make […]
