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.
