Image response - Wikipedia, the free encyclopedia Image response (or more correctly, image response rejection ratio, or IMRR) is a measure of performance of a radio receiver that operates on the super-heterodyne principle. [1] In such a radio receiver, a local oscillator (LO) is used to heterodyne or "be

Superheterodyne receiver - Wikipedia, the free encyclopedia In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was i
