可产生矩形脉冲和正弦信号，矩形脉冲的脉宽可以改变，正弦信号则可以改变频率和时宽-Can produce rectangular pulse and sinusoidal signal, the rectangular pulse width can be changed, sinusoidal signal can be changed when the frequency and width

Matlab程序，GUI窗口 用FFT程序计算有限长度正弦信号y=sin(2*pi*f*t) ,0<=t<=N*T-FFT program calculate the finite length of the sinusoidal signal y = sin (2* pi* f* t), 0 < = t < = N* T respectively the DFT results obtained and analyzed and discussed in the fol

本文利用软件相移技术得到相互正交的参考正弦波信号；通过互相关算法，完成了软正交矢量型LIA相关器的具体实现；利用该方法实现了对微弱信号幅值和相位的检测，有效地抑制干扰，减少了硬件电路成本。通过Matlab仿真，验证了该算法具有一定的优越性。-In this paper, the software technology is orthogonal to the phase shift of the reference sine wave signal through cross-correlat

本程序是由matlab编写的频谱分析仪器，可以生成正弦、方波、三角波或混有白噪声的信号，还可以对信号进行指定点数的频谱分析。-This program is written by the matlab spectrum analysis instrument that can generate sine, square, triangle, or mixed with white noise signal, you can also specify the signal spectrum ana
