Abstract

Resistance balancing in wave filters to overcome the effect of dissipation losses was proposed by W. P. Mason with particular reference to lattice and bridged "T" filter sections employing piezo-electric crystals, and by H. W. Bode in reference to the balancing of losses at rejector frequencies in m-derived filter sections. An examination of the two methods indicates that their direct application is very limited; but Mason's method, considered in relation to filters designed after methods due to Cauer and Bode, and employing piezo-electric crystals, is an important contribution to filter design. These methods taken together should make it possible to approach closely to ideal filter characteristics.
