- LINEINTRGAL Line Integral in a 2D Vector Field. LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C. X and Y define the coordinates of a rectangular grid over which U and V are defined. X and Y must be monoto
单频脉冲
- 单频脉冲 close all;clear all;clc; x=-5:0.05:5; y=-1:0.05:1; [X,Y]=meshgrid(x,y); T=5; b=pi*Y.*(T-abs(X))+eps; c=((sin(b).*(T-abs(X)))./(T*b)); Z=abs(c); surf(X,Y,Z),title('单载频矩形脉冲信号模糊图'),xlabel('时间'),ylabel('频率');
ding
- 选取windows系统自带的ding.wav信号作为分析对象，在Matlab软件平台下，利用函数wavread对音频信号进行采样，记住采样频率和采样点数，听一下原始声音sound(y, fs, bits)。 （2）音频信号的频谱分析，先画出音频信号的时域波形；然后对音频号进行快速傅里叶变换fft(y,N)，N取32768，画出信号的频谱特性，加深对频谱特性的理解。 （3）根据频谱，反演时域特性，画出时域波形。寻找幅值最大的两个频率，此频率除以fft点数在乘以采样频率就是信号的主频，即可合
