Image rejection ratio — In reception using heterodyning in the tuning process, the image rejection ratio, or image frequency rejection ratio, is the ratio of (a) the intermediate frequency (IF) signal level produced by the desired input frequency to (b) that produced by … Wikipedia
Image frequency — Image frequency: In radio reception using heterodyning in the tuning process, an undesired input frequency that is capable of producing the same intermediate frequency (IF) that the desired input frequency produces. In a heterodyne receiver… … Wikipedia
Image response — (or more correctly, image response rejection ratio, or IMRR) is a measure of performance of a radio receiver, particularly one that operates on the super heterodyne principle.In such a radio receiver, a local oscillator is used to heterodyne or… … Wikipedia
Image Quality — is a characteristic of an image that measures the perceived image degradation (typically, compared to an ideal or perfect image). Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an … Wikipedia
