自制软件，实现频谱分析。能显示信号与频谱图。主要是对正弦信号和三角波进行一维FFT变换，得到频谱图。-Self-made software, the realization of spectral analysis. Showing the signal and frequency spectrum. Mainly sinusoidal signal and triangular wave transform one-dimensional FFT, the frequency spectrum

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
