Abstract

A discrete‐time, second‐order notch filter is employed to study the microwave bandstop filter. By equating the system function of the second‐order notch filter to the transfer function of a serial line shunted with an equal‐length, two‐section open stub, simple and explicit expressions dictating the bandwidth and center frequency of a microwave bandstop filter are obtained. Experimental results are presented to illustrate the validity of this design method. © 2008 Wiley Periodicals, Inc.

## Abstract A new method for the design of a bandstop filter is presented. The two‐section open stub is employed to emulate a notch filter in the discrete‐time domain. A cascade connection of two‐section open stubs with proper frequency scaling serves to represent a bandstop filter of wider stopban

Half-band filters are a class of important filters among digital filters, and have been widely used in many applications such as filter banks and wavelets. The conventional methods are mainly concerned with FIR half-band filters with exactly linear phase. However, the exactly linear phase filters ha
