⎯ This paper presents the tunable technique of the analog filter at high frequency fp = 1 MHz by used the Fractional-order ( ) n α + step, where n is an original of integerorder on circuit and α is an approximation order step 0 1 α < < , An approximation order is designed from the Fractance circuits, and also presents the approximation function of the Fractional-order Laplacian sα design on the...

An electronically tunable voltage-mode universal biquadratic filter with one input and five output terminals employing differential difference current conveyor transconductance amplifiers (DDCCTAs) has been proposed. The proposed circuit uses only two DDCCTAs, two grounded resistors and two grounded capacitors. It can realize all the five standard biquadratic filter functions, namely lowpass, b...

A new high input impedance voltage-mode universal biquadratic filter with three input terminals and six output terminals is presented. The proposed circuit uses three plus-type differential difference current conveyors (DDCCs), three resistors, and two grounded capacitors. The proposed circuit can realize all the standard filter functions, namely, lowpass, bandpass, highpass, notch, and allpass...

Polynomial and rational filters for image enhancement, edge preserving noise smoothing, and interpolation of encoded images are usually designed as a weighted combination of nonlinear filters having lowpass or highpass behaviour. The choice of the filter components and of the coefficients is performed heuristically, though. In this paper general design constraints for polynomial and rational fi...

Abtrac t This paper presents an FIR fllter system capable of implementing virtually any practical lowpass and highpass filter with as little as 60-60 multiplications per sample. The method b based on multirate techniques and complementary Alters. We first give a brief presentation of the principle and the necessary building blocks. Then, practical design methods for optimitation are presented t...

Direct computation of CWT using FFT requiresO(Nlog2N) operations per scale, whereN is the data length. The Shensa algorithm is a fast algorithm to compute CWT that uses only O(N) operations per scale. The application of the algorithm requires the design of a bandpass and a lowpass filter for a given mother wavelet function. Previous design method involves multi-dimensional numerical search and ...

This Classifying Bird Sounds (chip notes) project’s purpose is to reduce the unwanted noise from recorded bird sound chip notes, design a scheme to detect differences and similarities between recorded chip notes, and classify bird sound chip notes. The technologies of determining the similarities of sound waves have been used in communication, sound engineering and wireless sound applications f...
