What receiver stage combines a 14.25-MHz input signal with a 13.795-MHz oscillator signal to produce a 455-kHz intermediate frequency (IF) signal?
Mixer
A mixer is the stage that combines two input frequencies (RF and LO) to produce sum and difference frequencies. Here, 14.25 MHz (RF) - 13.795 MHz (LO) = 0.455 MHz = 455 kHz (IF).
