FIR(Finite Impulse Response)滤波器：有限长单位冲激响应滤波器，是数字信号处理系统中最基本的元件，它可以在保证任意幅频特性的同时具有严格的线性相频特性，同时其单位抽样响应是有限长的，因而滤波器是稳定的系统。因此，FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。 (FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications.)

ModbusRTU 功能模块,ModbusRTU协议是工业上最常见的通讯协议之一 本模块先前运用在PIC系列单片机上,稍作修改可以运用到其他场合.(ModbusRTU Modules For Embedded Development )

这个程序是用来雷达信号测距模拟的。这个信号时线性调频信号(This program is used to simulated radar signal ranging. Chirp signal when this signal)

本程序实现多模态故障检测与故障诊断，用的方法是PCA_GMM，GMM是用的FJ算法，效果很好(This procedure realize multimodal, fault detection and fault diagnosis method is PCA_GMM, GMM FJ algorithm is used, the effect is very good)

svpwm控制信号，可以通过此信号完成对三相整流或逆变电路的SVPWM控制。(svpwm control signal, the signal can be done by this three-phase rectifier or inverter circuit SVPWM control.)

说明：  通过实际采集到的数据，数显通过数据预处理，进行不良数据的清洗，然后通过PCA降维，k均值聚类提取运动学片段，建立运动学片段库，通过随机策略提取运动学片段构成汽车行驶工况。(Through the actual collected data, the digital display cleans the bad data through data pretreatment, and then extracts the kinematics fragments through PCA dimensionality reduction, K-means clustering, establishes the kinematics fragments library, and extracts the kinematics fragments through random strategy to form the driving conditions of the vehicle.)

Using the idea from Seam Carving for Content-Aware Image Resizing, the codes enables a selected image to resize without having distortion of important object in the image file.

Wavelet Subband coding for speaker recognition The fn will calculated subband energes as given in the att tech paper of ruhi sarikaya and others. the fn also calculates the DCT part. using this fn and other algo for pattern classification(VQ,GMM) speaker identification could be achived. the progress in extraction is also indicated by progress bar.(Wavelet Subband coding for speaker recognitionThe fn will calculated subband energes as given in the att tech paper of ruhi sarikaya and others.
