数字控制振荡器（NCO，numerical controlled oscillator）是软件无线电、直接数据频 率合成器（DDS，Direct digital synthesizer）、快速傅立叶变换（FFT，Fast Fourier Transform） 等的重要组成部分，同时也是决定其性能的主要因素之一，随着芯片集成度的提高、在信号 处理、数字通信领域、调制解调、变频调速、制导控制 ...

In number theory, the Euclidean algorithm (also called Euclid s algorithm) is an algorithm to determine the greatest common divisor (GCD) of two elements of any Euclidean domain (for example, the integers). Its major significance is that it does not require factoring the two integers, and it is also ...

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 ob ...

Abstract - A &#64258 exible multiscale and directional representation for images is proposed. The scheme combines directional &#64257 lter banks with the Laplacian pyramid to provides a sparse representation for two- dimensional piecewise smooth signals resembling images. The underlying expansion is ...

SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. It is used in countless desktop computer applications as well as consumer electronic devices includi ...

Main program running when workpiece is ready on deferent belt(deferent_ready=ture). * Call Square_Wave subroutine to generate 0.5ms square wave on P1.2 to drive * electromotor,then drive deferent belt step forward. When it steps to the measure * zone, it stops to be me ...

matlab有限元网格划分程序 DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed ...

      Use the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its spectrum linearly and logarithmically. Apply Hamming window to reduce the leakage.   .   The hamming window can be coded in Matlab ...
