Home > Image rejection ratio

Note 1: The image rejection ratio is usually expressed in dB. Note 2: When the image rejection ratio is measured, the input signal levels of the desired and image frequencies must be equal for the measurement to be meaningful. Synonym: image frequency rejection ratio.

Image antennaIn telecommunication, an image antenna is a hypothetical mirror-image, i. virtual-image, of an antenna, i. antenna element, considered to extend as far below ground, i. the ground plane, as the actual antenna is above the ground plane.

The term image arises from the mirror-li Image rejection ratioImage rejection ratio In reception using heterodyning in the tuning process, the ratio of (a) the intermediate- frequency (IF) signal level produced by the desired input frequency to (b) that produced by the image frequency.

It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can Image compressionImage compression is the application of data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form. Image compression can be lossy or lossless. ImageIn common usage, an image (from Latin imago or picture is an artefact that reproduces the likeness of some subject—usually a physical object or a person. Images may be two-dimensional (e. a photograph) or three dimensional (e. a statue).
