What Is a Linear Amplifier?
A linear amplifier, often referred to as a linear amp, ensures that the output signal’s waveform directly correlates with the input signal’s waveform, maintaining signal fidelity.
This type of amplifier is pivotal across a wide array of applications, including audio systems for pristine music playback, communication devices for clear signal transmission, measurement tools for precise waveform analysis, and broadcasting equipment for undistorted signal dissemination.
Linear amplifiers are primarily divided into Class A and Class B categories. Class A amplifiers, by keeping transistors active at all times, offer superior output quality at the expense of increased power usage. Conversely, Class B amplifiers, which activate transistors in response to the input signal, are more energy-efficient but may compromise on sound quality.
