Antimetric

adjectiveStandard termElectronics

Describes a two-port circuit having an input image impedance that acts as the reciprocal of its output.

Within filter design, an antimetric circuit exhibits a specific duality in its electrical properties. The normalized impedance at one terminal functions as the mathematical reciprocal of the opposite terminal. Such behavior differs fundamentally from symmetric designs, which require matching impedances. This property remains essential for synthesizing targeted frequency responses in various filter topologies.
