text: In a simple superheterodyne receiver, the incoming radio frequency signal (at frequency f I N {\displaystyle f_{IN}} ) from the antenna is mixed with the VFO output signal tuned to f L O {\displaystyle f_{LO}} , producing an intermediate frequency (IF) signal that can be processed downstream to extract the modulated information.
