A new approach is suggested to approximate the amplitude frequency behaviour of a given high Q poles network function, by an explicit function having poles with a predetermined desired low Q , and with explicit knowledge and control of the error. The method is practical for reducing Q 's by the ratio of up to 6. Any critical pole‐pair is replaced by an approximating function possessing a complex conjugate n ‐th order pole‐pair and a ( n −1)‐th order zero‐pair. A general second order low Q building block is derived as an example. Measured results proving the practical usefulness of the method, are reported.
