답변:Hiro Yoshino2020년 2월 19일 I have excel file which consists of readings of time and corresponding amplitude of Vibration analysis. I have to do signal processing for Vibration analysis. First, I have to plot time domain graph and then convert it into frequency domain using FFT...
This chapter introduces the basic concepts of the time domain, the frequency domain, and transformations between the two in the context of our continuing study of Matlab. Subsequent engineering courses study the subject in great depth, so our goal is to use Matlab to develop a foundational ...
The Linear Time/Frequency Toolbox (LTFAT) is a Matlab/Octave toolbox for doing time-frequency analysis. It is intended both as an educational and computational tool. The toolbox provides the basic Gabor, Wilson and MDCT transform along with routines for constructing windows (filter prototypes) an...
For detailed information about representing time-domain and frequency-domain data in MATLAB®, seeRepresenting Data in MATLAB Workspace. You can transform your data from one domain to the other. The table summarizes the commands for transforming data between the time and frequency domains. For more...

You're missing the scaling of the fft() output by the length of the input signal. That is likely the biggest contributor to why your scale is off. See how a unit amplitude sine wave below ends up as unit magnitude in the frequency domain.
For linear and nonlinear ODEs (grey-box models), you can specify any ordinary differential or difference equation to represent your continuous-time or discrete-time model in state-space form, respectively. In the linear case, both time-domain and frequency-domain data are supported. In the nonli...
用matlab生成谐波代码从时频分布中提取时频轨道 使用Matlab代码从时频分布(TFD)中提取时频轨迹,这些轨迹代表了瞬时频率(IF)定律。 根据Rankine等人的工作提出了两种方法。 (2007)和McAulay-Quatieri(1986); 中的详细信息。 要求: Matlab(R2013或更高版本,)。
