Demodulator

A demodulator is a device or circuit that extracts information from a received signal in communication systems. When data is transmitted wirelessly or through cables, it is often combined with a carrier wave through a process called modulation. The demodulator's role is to reverse this process, separating the original signal or message from the carrier wave. This allows the receiver to access the transmitted information, such as audio, video, or data. Essentially, it translates the complex signal back into a usable form so that the intended content can be understood or processed further.
