What Is an Analog Amplifier?
An analog amplifier is essential in analog signal processing, designed to enhance the strength of electrical signals. It operates on various signal forms, including voltage, current, and power, typically realized through integrated circuits known as operational amplifiers (op-amps).
Its application spans a broad range of devices and systems, from audio equipment and wireless communication devices to sensor signal enhancement and control systems. Beyond mere signal amplification, analog amplifiers are pivotal for filtering, waveform shaping, and signal conversion, proving indispensable in electronics such as medical equipment.
