Abstract :
Rules for transmission zero movement in real circuit cross-coupled filters and a classification of two primary transmission zero types are given. The rules and classifications apply to filters of arbitrary bandwidth and give insight into response skewing and "disappearing" zeros. Transmission zero sensitivity and performance limitations are described and related to circuit topology and coupling element types.
