    Image, Multiple, and Out-of-Band Responses Image responses are due to input signals that are two times the IF frequency above or below the tuned frequency. Multiple responses are due to input signals mixing with more than one LO harmonic. Out-of-band responses are due to input signals outside of the selected frequency band.
