• Image impedance — is a concept used in electronic network design and analysis and most especially in filter design. The term image impedance applies to the impedance seen looking in to the ports of a network. Usually a two port network is implied but the concept… …   Wikipedia

• Image filter end terminations — For an overview of image filters see composite image filter. Filters designed using the image impedance methodology suffer from a perculiar flaw in the theory. The predicted characteristics of the filter are calculated assuming that the filter is …   Wikipedia

• Mm'-type filter — The mm type section has two independent parameters (m and m ) that the designer can adjust. It is arrived at by double application of the m derivation process. Its chief advantage is that it rather better at matching in to resistive end… …   Wikipedia

• antimetric — adjective a) The converse of symmetric in electrical network theory, especially filter theory. A network where the input and output image impedances are the dual, or inverse, of each other as opposed to symmetric networks where they are equal. A… …   Wiktionary
