Overview
An amplifier is an electronic device that increases the magnitude of a signal, utilizing electric power from a power supply to amplify the amplitude of a signal applied to its input terminals. With a wide range of applications, amplifiers are fundamental to modern electronics, found in almost all electronic equipment, from audio equipment to medical devices. The amount of amplification provided by an amplifier is measured by its gain, which is the ratio of output voltage, current, or power to input. Amplifiers can be categorized by the frequency of the electronic signal being amplified, such as audio amplifiers, radio frequency amplifiers, and microwave amplifiers. Amplifiers are a crucial component in many modern technologies, including smartphones, computers, and televisions.
🎵 Origins & History
The concept of amplification has been around for centuries, with early examples including the use of horn-shaped devices to amplify sound. Amplifiers are used in a wide range of applications, from audio equipment to medical devices, and are a crucial component in many modern technologies, including smartphones, computers, and televisions.
⚙️ How It Works
An amplifier works by using electric power from a power supply to increase the amplitude of a signal applied to its input terminals.
