It is usually composed of an antenna, a tuner, a demodulator and an output stage. The antenna is used to receive radio signals, and the tuner is used to convert the received signal into an intermediate frequency signal. The demodulator further restores the intermediate frequency signal to the original signal for subsequent processing. The output stage is used to output the demodulated signal to external devices, such as speakers or LCD screens.
