地震中常用的一些偏移程序，挺有用处的，跟大家分享一下(Seismic shift in a number of commonly used procedures, quite useful to share with you)

说明：  声级计自动检定系统设计,介绍如何检定声级计.(Automatic verification system for sound level meter design, how to test the sound level meter.)

有借鉴意义哦，小波包分析提取振动信号中的特征频率，计算晶粒的生长，入门级别程序。( There are reference Oh, Wavelet packet analysis to extract vibration signal characteristic frequency, Calculation of growth, entry-level program grain.)

说明：  example of the fuzzy logic in simulation

本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)
