Many existing fundamental frequency recognition (FFR) algorithms return reliable results when the analysis window is suuciently wide. In some applications, however, the response time, i.e., the sum of the width of the analysis window and the computation time for the FFR algorithm, must be made as short as possible. This paper studies the eeect of window width on the accuracy of two FFR algorith...

Lattice images formed by plasmon energy-loss electrons in an energy-filtered transmission electron microscope are compared for different experimental parameters. The image resolution is primarily determined by chromatic aberration which is controlled by the width of the energy selection window. With an energy slit 3 eV in width, the plasmon loss electron image shows the same resolution and cont...

In this paper bandpass filter has been designed and simulated using different windows techniques. Blackman, Hamming and Kaiser Windows techniques are used for design of bandpass filters using matlabs. The performances of all designs have been compared in terms of sidelobe attenuation and mainlobe width. The simulated result shows that Blackman window gives maximum mainlobe width as compared to ...

The aim of this paper is that it shows the dynamics response of speed with design the fuzzy logic controller to control a speed of motor for keeping the motor speed to be constant when the load varies. In recent years, the field oriented control of induction motor drive is widely used in high performance drive system. It is due to its unique characteristics like high efficiency, good power fact...

Linearity of values of rectified and integrated EMG signals with frequency of incidence of action potentials in muscle fibers and the effect of moving average window width on the range of values of integrated signals was tested on theoretical model. Our simulations of 4 overlapping single units multipotential signal demonstrated that integrated EMG signals are only approximately linearly propor...

A technique determines the optimal window width for orbiting rod transmission studies in positron emission tomography (PET). Windowing reduces noise in orbiting rod transmission studies. Lines-of-response (LOR) which intersect the rods generate primarily true coincidence events. LOR which pass far from the rods generate random and scatter events. Since the angular position of the orbiting rods ...

Abstract – This document gives you a brief idea of the Design and simulation of DC/DC Boost converter using pulse width modulation based sliding mode controller operating in continuous conduction mode is discussed. The performance and properties of sliding mode controller is compared with conventional controllers Proportional Integral Derivative (PID) controller and Proportional Integral (PI) c...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
