The FNAL 9-cell 3.9GHz deflecting mode cavity designed for the CKM experiment was chosen as the baseline design for the ILC BDS crab cavity. The full 9cell CKM cavity including the coupler end-groups was simulated using the parallel eigensolver Omega3P and scattering parameter solver S3P. It was found that both the notch filters for the HOM/LOM couplers are very sensitive to the notch gap, whic...

-The electrocardiogram has considerable diagnostic significance, and application of ECG monitoring are diverse and in wide use. For diagnosticquality ECG recordings, signal acquisition must be noise free. The signal acquisition is susceptible to the interference from other biological and environmental sources. This article presents the application of the digital IIR filter on the raw ECG signal...

A novel photonic microwave discrete-time finite-impulse response filter is created by spectrally slicing a supercontinuum source, generated from a mode-locked laser. We experimentally demonstrate a four-tap filter with a 28.16 dB extinction ratio. Comparison between measured and predicted magnitude responses shows an excellent match in the performance of the notch filter across the entire bandw...

A microstrip ultra-wideband (UWB) filter with unique shape, compactness, simplicity of operation and flexible notch characteristics is introduced. It is based on the fundamental and harmonic characteristics of a 50 Ohm transmission line that is grounded at both ends. The filter possesses design flexibility in the sense that it can operate as a stand-alone UWB component or include simple additio...

This paper explores the use of imprecise computing to develop digital filters with adaptive length in order to meet real-time constraints. A large-order filter typically provides better filtering but takes longer to compute than a low order filter. An adaptive length filter can provide a resource manager with alternatives that can be used if resources become scarce. This paper discusses the use...

Radio Frequency Interferences (RFI), such as strong Continuous Wave (CWI), can influence the Quality of Service (QoS) communications, increasing Bit Error Rate (BER) and decreasing Signal-to-Noise Ratio (SNR) in any wireless transmission, including a Digital Video Broadcasting (DVB-S2) receiver. Therefore, this paper presents an algorithm for detecting mitigating Multi-tone Interference (MCWI) ...

A second order voltage mode tunable universal filter is presented. The voltage mode filter is based on dual output second generation current controlled current conveyor (DOCCCII). The filter is capable of realizing high pass (HP), low pass (LP), band pass (BP), notch pass (NP) and all pass (AP) responses in voltage mode (VM). The filter employs only two capacitors and hence enjoys minimum compo...

The aim of this paper is to present a comparison of some popular methods for online harmonic estimation. The wellknown methods Descrete Fourier Ttransform (DFT), Enhanced Phase Locked Loop (EPLL), Adaptive Notch Filter (ANF) and method based on Extended Kalman Filter (EKF) are simulated and compared. The methods are compared in critical phases, such as the fast change of harmonic amplitudes and...
