In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

We present experimental and finite-difference time-domain simulation studies on high pass filter (HPF) based on transverse electric (TE) mode, low pass filter based (LPF) on multiple slits, and tunable notch-filter based on single slit. The LPF and notch filter are carried out by using the metal slits positioned at the center of the air gaps in tapered parallel-plate waveguides (TPPWG).

This paper presents application of Neural classifier with High pass filter(HPF) to examine its own functional health, to speed up test time and to facilitate fault diagnosis Here we presents an application to insert a built in test block to test any complicated analog circuit in terms of performance while considering tolerance factor. Testing block which is to be added in the chip contains Syna...

the key point of super resolution process is the accurate measuring of sub-pixel shift. Any tiny error in measuring such shift leads to an incorrect image focusing. In this paper, methodology of measuring sub-pixel shift using Phase correlation (PC) are evaluated using different window functions, then modified version of (PC) method using high pass filter (HPF) is introduced . Comprehensive ana...

In this paper, we simulated series arc on electric heaters, vacuum cleaners and incandescent lamps controlled by a dimmer to analyze the characteristics of series arc that causes electric fires. A high pass filter (HPF) was designed to detect arc signal only. The HPF consists of 2-stage coupling capacitors and detection impedance, and its low cut-off frequency of -3 dB was estimated to 3 kHz. B...

A transient damping method (TDM), introducing the frequency of a virtual synchronous generator through high-pass filter (HPF) to power reference, is usually adopted stabilize system against disturbances. However, different from small-signal stability perspective, this letter reveals that gain H...

The performance of a high pass filter (HPF) and a band pass filter (BPF) with and without defected ground structure (DGS) was analyzed in this specific work. The Defected ground structure includes rectangular and circular etched shapes in ground plane. Calculation and comparison of the response of both filters was done separately. Parameters of the proposed configuration were calculated at the ...

A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...

in this paper, gaussian and elliptic high pass filters are analyzed for image sharpening qualitatively and quantatively . the filters are implemented in frequency domain using matlab software. experiments are performed to compare the performance of both the filters ,processed images are presented. the results demonstrate that elliptic yields better results.

This research studies the perceptual evaluation of speech signals using an inexpensive recording device. Different types noise-reduction and electronic enhancement filters viz. Hamming window, high-pass filter (HPF), Wiener-filter no-speech activity-cancelling were applied in compliance with testing conditions such as P.835. In total, 41 volunteers participated study for identifying effects tho...
