Modulation recognition of MQAM signals in the passband;

Without increasing the size of the microstrip, the bandwidth of stopband or passband of the novel PBG microstrip line can be changed when the dispersion between the central frequency of PBG st.

Analytical formulae are presented for design of the passband equiripple Chebyshev filters.

Finite integration technique (FIT) is used to simulate the effects of shape change and optical printing precision on resonant frequency and the pass band of negative refractive index material.

Study on ultra-narrow band pass filter used for lightning detection;

All-fiber acousto-optical tunable band pass filter with sandwich fiber structure;

The paper depicts a sampling process based on band pass sampling theorem and using band pass signal under disturbances from a direct current.

Another Approach for Sampling of Compound Bandpass Signal;

A novel bandpass filter based on SIW and defected ground structure;

Two-path Bandpass ∑△ Modulator Design;

One of the applications is to digitize the signal at intermediate frequency in a super-heterodyne receiver with a band-pass Sigma-Delta modulator.

By improving the conventional filter anticipated aberrance design method, a new design method of band-pass filter is proposed, which can solve the problems between the narrow band and linear phase in adapting the direct coupling capacitance or inductance.
