Power Amplifiers
Power amplifiers are electronic devices that increase the strength of audio or radio signals, allowing them to drive larger speakers or transmit over longer distances. They take a weak input signal and boost its voltage, current, or power while preserving the original signal's quality. This makes them essential in sound systems, broadcasting, and communications, where clear and powerful signals are needed for effective audio playback or transmission. In essence, they act as the final step in amplifying signals to a level suitable for output or transmission.
