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.
