The correction of gravity observations with band-pass filters
can improve the signal-to-noise ratio of weak signals in the elaboration of long period normal mode seismology.
In each replication, we apply the band-pass filter
to the artificially generated sample and calculate the correlations in the filtered components.
By refining the internal conductors and making the dielectric layers thinner, TDK successfully created a 1005-size, third-order band-pass filter
with three resonators.
This model, in turn, is used to forecast and backcast 300 observations, and the 600-term band-pass filter
is applied to the resulting series.
These band-pass filters
consist of digital high- and low-pass filters each with 48 dB/octave steepness.

The seeker could use two different detectors to monitor the energy levels in the two bands (for example, lead sulfide for the short band and indium antimonide for the long band) or use a single detector with different band-pass filters
on the reticle spokes.
Customers can also choose the optical filters such as IR-pass filters, IR band-pass filters
, NIR notch filters etc.
As studied in , for a ring resonator band-pass filter
, two TZs are produced in the lower and upper cutoff edges of the desired pass band resulting from electric currents in the two propagation paths (Path 1 and Path 2) canceling each other.

Moreover, a novel resonator-embedded band-pass filter
, which is constructed by four proposed nested resonators, is designed and realized, and the good characteristics of the novel resonator structure have been verified by experiment results.
It acts as a band-pass filter
in the microwave frequency range and it can be also used in sensor applications.
