A receiver receives an incoming signal of 3.54 MHz, and the local oscillator produces a signal of 3.995 MHz. To which frequency should the IF be tuned?
455 kHz
The intermediate frequency (IF) is the difference (or sum) between the received frequency and the local oscillator frequency. 3.995 MHz - 3.54 MHz = 0.455 MHz = 455 kHz.
