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...
Transform time-domain data to the frequency domain. You can specifyN, the number of frequency values. To transform time-domainiddataobjectt_datato frequency-domainiddataobjectf_datawithNfrequency points, use: f_data = fft(t_data,N)
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 ...
function to compute the frequency spectrum. There is an example provided in the documentation, adapt it to your data.
This MATLAB function estimates a discrete-time state-space model sys of order nx using data, which can be time-domain or frequency-domain data.
how to using fft to change pulse in teh time... Learn more about fft, timedomain, frequencydomain, pulse
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.
