The manufacture method of a high frequency piezoelectric ceramic electric filter and its are introduced in this paper. The ceramic filter with double energy trapped mode is made up of piezoelectric material Pb(Zn_(1/3) Nb_(2/3))(ZrTi)O_3 doping with Ce and Mn ,and has the advantages of small insertion loss, large stop-band attenuation and high temperature stability.
In the general SIR electric filer, a λ/4 transmission line resonator is added to get additional resonant vibration point in stopband and improve the performance of attenuation pole and stray resonant vibration of the electric filter.
We characterize the wavelet multipliers, as well as the scaling function multipliers and low pass filter multipliers.
For compactly supported gm, n (FIR filter banks) we prove an exponential rate of convergence and derive explicit expressions for the involved constants.
This, in turn, is used for designing local orthogonal bases obtained by unitary transformations of a single prototype filter.
This in turn, is used for designing local orthogonal bases obtained by unitary transformations of a single prototype filter.
The measure for uncertainty is a product of two factors evaluating the frequency selectivity in comparison with the ideal filter and the effective length of the filter in the digital domain, respectively.
The main purpose of this paper is to give a procedure to "mollify" the low-pass filters of a large number of Minimally Supported Frequency (MSF) wavelets so that the smoother functions obtained in this way are also low-pass filters for an MRA.
This phenomena is related to the invariant cycles under the transformation We also give a characterization of all low-pass filters for MSF wavelets.

Robust autopilot with wave filter for ship steering
A ship's dynamic model with wave disturbances was built and a wave filter was designed by means of an extended states observer (ESO).
According to ZBJ65015-89 standard about noise level testing method of woodworking tool, the noise testing for MJ90# and MJC1125 precision panel saws was conducted by using model ND2 precision sound-level apparatus and double frequency wave filter.
Our data on the spectral absorbance of the lens and visual pigment of these fishes suggest that the lens pigmentation acts as a short-wave filter to improve acuity of the visual system.

Shaking Optimization for Electric Filter Corona Electrodes
The advisability of tinting glass mixture in the feeder channel using electric filter dust is demonstrated.
An automated system for controlling the operation of shaking elements of electrodes (aeroridges) is suggested, which cleans the electrodes of the electric filter synchronously with the system of pneumatic removal of ash.
