Although the Kalman filter (KF) is widely used in practice, its estimated results are optimal only when the system model is linear and the noise characteristics of the system are already exactly known. However, it is extremely difficult to satisfy such requirement since the uncer
Harmonic Mitigation Using Inverter Based Hybrid Shunt Active Power Filter
With the rapid developments and use of non linear loads, the controlling over the harmonic current to get and maintain power quality is becoming more important. Active power filters has been used to compensate the harmonic pollution in our power system. This paper presents a effi
Design and Implementation of Fft Filter Using Vhdl Ip Core Based Design
The FIR FFT core is intended for the signal filtering. With the FIR filter of large impulse response length which exceeds up to Ni = 512 samples. Each FFT iteration dates are computed by the computational unit, called FFTDPATH, another words, data path for FFT calculations. FFTDP
Multi-scale Graph-based Guided Filter for De-noising Cryo-Electron Tomographic Data
Cryo-Electron Tomography is a leading imaging technique in structural biology, which is capable of acquiring two-dimensional projections of cellular structures at high resolution and close-to-native state. Due to the limited electron dose the resulting projections exhibit extreme
String-based learning in networks of evolutionary processors with filtered connections
This paper presents some connectionist models that are widely used to solve NP-problems. Most well known numeric models are Neural Networks that are able to approximate any function or classify any pattern set provided numeric information is injected into the net. Neural Nets usu
Choice of Filter Order in Lpc Analysis of Vowels
In studies of vowel perception and production, the formants of the signal are usually estimated using Linear Predictive Coding (LPC) analysis. The order of the LPC filter is typically estimated by starting with a heuristic value (e.g. the sampling frequency in kHz) and adjusting
Tunable RF Notch Filters for Blocker Suppression
Periodically time-variant passive 8-path notch filters are demonstrated in 65nm CMOS technology, with a notch frequency tunable from 100MHz to 1.2GHz with a clock signal. In a 50Ω environment, filter insertion loss in the pass band is 1.4-2.8dB, while the rejection at the notch f
A Time/Frequency Spectral Based Approach to Filtering
This report describes a new filtering approach suitable for demodulating narrowband signals captured in digital wideband data. The new approach is based on generating the filtered and downconverted baseband signals using time/frequency spectral data, rather than the input wideban
Active Filters for Video - AN3172
Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the
Effects of flow rates and composition of the filter, and decay/ingrowth correction factors involved with the determination of in situ particulate 210Po and 210Pb in seawater
Accurate measurements of particulate 210Po (Pop) and 210Pb (Pbp) are required in the investigation of (i) partitioning of Po and Pb between particulate and dissolved phases and (ii) export estimates of carbon and other key trace metals from the euphotic zone via sinking particula
