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 ...
This example shows how to transform time-domain data into the frequency domain using the FFT block. Note: To open the example and the associated models, you must have MATLAB® open. Use the Sine Wave block to generate two sinusoids, one at 15 Hz and the other at 40 Hz. Use the ...
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...
