Cutoff frequency

View this topic in
In physics and electrical engineering, a cutoff frequency, corner frequency, or break frequency is a boundary in a system's frequency response at which energy flowing through the system begins to be reduced rather than passing through. (Wikipedia.org)

A generalized |ω|-filter for 3-D reconstruction

Kwoh, Y.S.; Reed, I.S.; Truong, T.K. Nuclear Science, IEEE Transactions on, 1977

The 3-D reconstruction of a density function is based on a direct convolution algorithm developed first by Ramachandran and Lakshiminarayanan. Their method adopts a particular choice of weighting function or filter which is called here an |ω|-filter. In some cases this choice of filter had an undesirable oscillatory response. To remedy this problem Shepp and Logan found a weighting function ...


Compact miniaturized stepped-impedance low pass filters with a broad stopband

Yi-Chyun Chiou; Jen-Tsai Kuo; Chen, J. Microwave Conference Proceedings, 2005. APMC 2005. Asia-Pacific Conference Proceedings, 2005

Stepped-impedance low-pass filters (LPFs) are designed to have a miniaturized area and good rejection in wide stopband. The low-Z sections are implemented by microstrips loaded with periodic open-circuit stubs. Adjacent low-Z sections have a strong capacitive coupling through an interdigitated configuration. Equivalent circuit model for the interdigital capacitor is established for CAD purpose. In the stopband of the LPF, through ...


A Miniaturized and Broadband Balun Using Artificial Coupled Line With Imaginary Even-Mode Impedance

Chung-Hao Tsai; Iat-In Ao Leong; Hung-Chuan Chen; Tzong-Lin Wu Microwave Theory and Techniques, IEEE Transactions on, 2011

A broadband and miniaturized balun is proposed using the artificial coupled line with the imaginary even-mode impedance. The artificial coupled line is a metamaterial transmission line with zero electrical length for the even-mode excitation, whereas it behaves like a TEM transmission line with approximately constant characteristic impedance for the odd-mode excitation. Based on the artificial coupled line, a new concept ...


Monte Carlo simulation of InGaAs/strained-InAs/InGaAs channel HEMTs considering self-consistent analysis of 2-dimensional electron gas

Endoh, A.; Watanabe, I.; Mimura, T. Indium Phosphide and Related Materials (IPRM), 2012 International Conference on, 2012

We calculated the unstrained and the strained band structures of InAs and carried out Monte Carlo simulation of InGaAs/strained-InAs/InGaAs composite channel high electron mobility transistors (HEMTs) considering 2-dimensional electron gas (2DEG) self-consistent analysis by solving Schrödinger and Poisson equations. With considering the effect of 2DEG, the drain-source current Ids decreases. However, the negative threshold voltage shift due to the short-channel ...


Investigation of disc-type sensors using the UHF method to detect partial discharge in GIS

Yang Xu; Weidong Liu; Wensheng Gao Dielectrics and Electrical Insulation, IEEE Transactions on, 2015

The disc-type UHF sensor is considered among the simplest couplers for partial discharge (PD) detection in gas-insulated switchgear (GIS). This paper mainly focuses on the improvement of the sensitivity of the disc-type sensor. Disc- type sensors with different dimensions were tested on a 220 kV model GIS to find the critical parameters that determine the sensitivity of the sensor. The ...
