arithmetic symmetry

arithmetic symmetry

[¦a·rith¦med·ik ′sim·ə·trē]
(electronics)
Property of a band-pass or band-rejection filter whose graph of amplitude versus frequency is symmetrical around a center frequency; that is, the left-hand side of the response is a mirror image of the right-hand side.

Conventional exact transform bandpass filters have a symmetrical response when plotted on a logarithmic frequency scale (geometric symmetry); however, it is typically arithmetic symmetry (a plot on a linear frequency scale) that is desirable.
None of the popular low pass to bandpass transforms have arithmetic symmetry.
In 1989 a low pass to bandpass transform was developed that complied with Carassa's rule and resulted in arithmetic symmetry.
