filter
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.)

GPSsignalgeneration
利用Matlab生成GPS C/A 码的基带信号。
(1)产生卫星PRN 号码为“5”的一组C/A 码;
(2)循环生成25 页的导航数据,GPS 时间可填入一固定的已知数值;
(3)生成C/A 码扩频信号,每个C/A 码码片给出4 个采样数据;
(4)基带信号采用方波信号,电平为0 和1,占空比为50 %,
不加入噪声,进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)
