A design of compact ultra wideband (UWB) microstrip bandpass filter (BPF) with tunable notch response of wireless communication system is presented in this paper. The five order bandpass filter was designed using optimum distributed highpass integrated with Defected Microstrip Structure (DMS). The bandpass filter was designed at wideband frequency from 2.96 GHz to 10.1 GHz. The insertion loss a...
Notch filters are integrated in plasma diagnostic systems to protect millimeter-wave receivers from intensive stray radiation. Here we present a design of a notch filter with a center frequency of 140 GHz, a rejection bandwidth of ∼900 MHz, and a typical insertion loss below 2 dB in the passband of ±9 GHz. The design is based on a fundamental rectangular waveguide with eight cylindrical cavitie...
An ECG signal is basically an index of the functionality of the heart. For example, a physician can detect arrhythmia by studying abnormalities in the ECG signal. Since very fine features present in an ECG signal may convey important information, it is important to have the signal as clean as possible. Power line interference may be significant in electrocardiography. Often, a proper recording ...
Virtual oscillator control (VOC) is a type of nonlinear grid-forming controller for dc/ac inverters. Compared with the droop method, original VOC has faster transient response in islanded mode. However, its output voltage always contains third-order harmonic, resulting significant third-harmonic current, especially grid-connected In order to eliminate this notch-type filter typically employed, ...
Ship detection using polarimetric synthetic radar (PolSAR) imagery attracts a lot of attention in recent years. Most notably, the detector notch filter (PNF) has been demonstrated to be effective for ship PolSAR imagery, which gives excellent performances. In this work, mathematical form one new PNF (NPNF) based on physical mechanisms targets and clutter is further developed partial targets. Th...
