This paper presents a dimensional synthesis method for designing wide-band quarter-wavelength resonator bandpass filters. In this synthesis method, an alternative lowpass prototype filter and the edge frequency mapping method are proposed and applied. The improved Kand J-inverter model with the exponent-weighted turns ratio is also proposed in order to incorporate the frequency dependence of in...

This paper determines coefficients of infinite-impulse response (IIR) using Simulated Annealing (SA). IIR filter is essentially a digital filter with Recursive responses. Since the error surface of digital IIR filters is generally nonlinear and multimodal, global optimization techniques are required in order to avoid local minima. In this paper heuristic way for the designing IIR filters is pre...

A family of digital parametric audio equalizers based on high-order Butterworth, Chebyshev, and elliptic analog prototype filters is derived that generalizes the conventional biquadratic designs and provides flatter passbands and sharper bandedges. The equalizer filter coefficients are computable in terms of the center frequency, peak gain, bandwidth, and bandwidth gain. We consider the issues ...

A voltage-mode multifunctional biquadratic filter with three input terminals and single output terminal is presented. The proposed circuit is constructed using only one differential voltage current conveyor (DVCC) as active element and minimum number of passive elements, namely two resistors and two capacitors. The circuit can simultaneously realize all five different biquadratic filtering lowp...

By introducing video-quality adaptation mechanisms into intermediate network equipments using active network technologies, we can provide users with video distribution services taking into account client heterogeneity in terms of available bandwidth, performance of client systems, and user’s preferences about video quality. In this paper, we implement the lowpass filter which is the quality adj...

We describe an automated detection algorithm that may be used to identify the percussion peak (P), tidal peak (T), dichrotic notch (N), and dichrotic peak (D) components of the intracranial pressure (ICP) signal. The algorithm uses a moving average filter to remove quantization error, a lowpass filter to identify the beat series, and a local search to identify the components of each beat. The a...

In this paper we present a new voltage-mode (VM) multifunction filter configuration using only two four terminal floating nullors (FTFNs) and five passive elements. The circuit with a single input and three outputs can simultaneously realise lowpass (LP), bandpass (BP) and highpass (HP) filter responses. The natural frequency ( 0 ω ) and the bandwidth ( /Q ω0 ) can be orthogonally controlled. T...

A novel current-mode active-only single-input and four-output (SIFO) universal filter using four plus-type second-generation current-controlled conveyors (CCCIIs), one operational transconductance amplifier (OTA) and two operational amplifiers (OAs) is presented. The circuit is fully programmable and implements simultaneously lowpass (LP), bandpass (BP), highpass (HP) and Notch (BS) functions w...

Novel designs of circular waveguide components for lowpass, highpass, bandpass, and bandstop applications are presented. The filters are formed by cascaded TM11-mode resonator sections which share a common axis, thus preserving the polarizations of input signals due to rotational symmetry. Moreover, the filters are smaller than standard TE11-mode bandpass filters. Basic design considerations ar...

The paper presents a novel method of structure for designing and implementation of hardware reduced FIR filter in mixed signal processing domain for parallel data processing. Supported by a review of the literature, the paper demonstrates that the proposed methodology is superior, economical and can be applied in to applications like biomedical and audio signals. The results show improved perfo...
