Abstract—This paper presents a voltage mode universal biquadratic filter with one input and five output terminals, realizing all the standard filter functions that are high pass, band pass, low pass, notch and all pass, without changing the circuit topology. The proposed circuit employs three plus-type differential difference current conveyors (DDCCs), three grounded resistors and two grounded ...

This paper presents semicircular microstrip low pass filter with the sharp rejection and wide stop band. The proposed filter design is based on the calculations of filter parameters from traditional Hi-Lo impedance method and is available in the literature of microstrip filter. To further improve the design performance, high impedance lines are magnetically coupled, resulting an attenuation pol...

The open distribution system simulator (OpenDSS) is open-source software developed by the Electric Power Research Institute (EPRI) in United States for analyzing systems. OpenDSS primarily used systems fundamental power flow (FPF) and harmonic (HPF). Single-tune high-order filters are generally combined to achieve a better filtering performance practical analysis applications. However, requires...

Image inpainting based on deep learning has been greatly improved. The original purpose of image was to repair some broken photos, such as artifacts. However, it may also be used for malicious operations, destroying evidence. Therefore, detection and localization operations are essential. Recent research shows that high-pass filtering full convolutional network (HPFCN) is applied achieves good ...

A novel ultra-wideband (UWB) bandpass filter (BPF) with a fractional bandwidth (FBW) of about % 110 is presented using the hybrid microstrip-defected-ground structure (DGS). The proposed filter was designed using a combination of hybrid microstrip-defected-ground structure lowpass filter (LPF) with typical quarter-wavelength short-circuited stubs highpass filter (HPF), followed by an optimizati...

So effectively, you can say that the capacitor acts as a low-pass filter when it in a transistor circuit, it blocks the DC and acts as a low impedance path for AC. Official Full-Text Publication: Single Transistor Active Filters: What is Possible and The results presented here fill both a circuit-theoretic gap and an application-oriented gap related to single a case is the low-pass filter numbe...

ABSTRACT A new current-mode universal active-RC filter is proposed. The proposed circuit is based on a new universal passive filter topology. Two Fully Differential Current Conveyors (FDCCII) are used to construct a universal active-RC filter from this passive filter. The FDCCII based proposed filter has only grounded resistances and capacitors as the passive elements. The circuit simultaneousl...
