Abstract :
Each triplet has the property of realizing a single real frequency transmission zero. Asymmetric filter responses can be realized by a cascade of triplet sections. This paper describes a Newton-Raphson method for rapid solution of the equations, which produces the desired coupling matrix for a CT topology.
