filters with multiband and high selectivity are attractive because they could meet the demand for multiband wireless communication systems.
According to the strength results, a multilayer inkjet-printed interdigital bandpass
filter was realized to demonstrate a high performance and cost-effective integration circuit for electronic package applications.

Since 2005, various UWB bandpass
filters have been designed and reported, including filters of composite lowpass and highpass structures , shorted-circuited stub filters  , multiple-mode resonator (MMR) structure filters , etc.

In the subbands decomposition, the Butterworth infinite-impulse-response (HR) bandpass
filter was used to decompose both pyroshock and laser shock signals into a set of time-domain signals with different frequency bands.
The inverting and noninverting low-pass, bandpass
, and high-pass filtering responses can be obtained simultaneously.
