RF demodulators are electronic circuits or devices used to extract baseband signals or modulation information from RF carrier signals. They perform the reverse process of modulation, recovering the original signal from the modulated RF waveform. RF demodulators are used in communication receivers, radar systems, wireless data transmission, and RF identification systems to retrieve information encoded in RF signals. They are essential components in RF receivers and demodulation circuits, enabling the extraction and processing of transmitted data or information.
