signal_analyzer
说明: 最近看到有人提问怎样用FFT实现频谱分析,我认为能够进行到频谱分析的人,对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程,发给大家参考一下。
历程主要内容(signal_analyzer.rar)如下:
test1.txt 第一列为时间t,0.001s为步长;第二列为系统的输入信号;第三列为系统的输出信号。
signal_analyzer.m首先将test1.txt 的数据读入workspace,然后进行FFT,分析出两信号的频率,输出对于输入的幅值衰减(db),输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)
