Linear Amplifier

A linear amplifier is a device that increases the strength of an electrical signal without changing its shape or information. It takes a weak input signal, amplifies it, and produces a stronger output signal that maintains the original signal’s characteristics. This is important in applications like audio systems, radios, and communication devices, where clarity and fidelity are essential. The term “linear” means the output is directly proportional to the input, ensuring the amplified signal remains true to the original. In essence, it boosts signals accurately while preserving their quality.
