RF Demodulators

Radio frequency demodulators are one type of modulators. A component that causes certain parameters or an optical or electrical signal, such as amplitude, intensity, frequency, or phase, to vary according to the pattern or another signal. Demodulator is a device that restores the low frequency digital signal modulated in the high frequency digital signal by digital signal processing technology. Demodulator is widely used in broadcasting (audio signal), television (video signal) and other information transmission and restoration. Demodulators and modulators are usually used in pairs. The modulator is used to process the digital signal to the high-frequency signal for transmission, and the demodulator is used to restore the digital signal to the original signal.
