High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

P3.20. Consider an analog signal xa (t) = sin (2πt), 0 ≤t≤ 1. It is sampled at Ts = 0.01, 0.05, and 0.1 sec intervals to obtain x(n). b) Reconstruct the analog signal ya (t) from the samples x(n) using the sinc interpolation (use ∆ t = 0.001) and determine the frequency in ya (t) from your plot. (Ignore the end effects.) C) Reconstruct the analog signal ya (t) from the samples x (n) using the cubic spline interpolation and determine the frequency in ya (t) from your plot. (Ignore the end effects.)

A digital filter structure for wideband filtering is proposed. It consists of two allpass filters and a linearphase FIR filter. One major advantage of this structure is that the allpass filters are functions of zM which implies that the maximal sample frequency is M times higher for this structure than for the corresponding conventional structures.

This paper analyzes the vector control theory of asynchronous motors based on the magnetic orientation of motor rotors, and its mathematical model is made. Then the variable frequency vector speed-adjusting experimental system is built with the DSP TMS320F2812 which works as the core control chip and intelligent power module.

In this paper, a new method is introduced to implement chaotic generators based on the Henon map and Lorenz chaotic generators given by the state equations using the Field Programmable Gate Array (FPGA). The aim of this method is to increase the frequency of the chaotic generators. The new method is based on the MATLAB® Software, Xilinx System Generator, Xilinx Alliance tools and Synplicity Synplify.

This software is developed to provide ease with controller design. For PID control, options are given to design and analyse the compensated and uncompensated system. You are free to choice among Proportional PI, PD and PID mode of control. Both frequency and time domain characteristics can be observed. Special Menus are given to observe time and frequency response plots. For Statefeedback controller similar options are given. But this is limited to second order system only.

This sample program generates two sine waves called X and Y. It will then calculate the normalized magnitude and phase of the two waveforms using the following formulas: Mag = sqrt(X^2 + Y^2)/sqrt(GainX^2 + GainY^2) Phase = (long) (atan2PU(X,Y) * 360) The program will prompt the user to change the gain and frequency of the X and Y waveforms.

Abstract—We describe a technique for image encoding in which local operators of many scales but identical shape serve as the basis functions. The representation differs from established techniques in that the code elements are localized in spatial frequency as well as in space.
