I have an excel file of FFT data including frequency, amplitude and phase of a bearing signal. I want to montitor the condition of the bearing using elvelope method. How can i plot x-t of the signal and also find envelope of this signal?
Open in MATLAB Online Hey guys, I am tring to export the fft analysis result from fft tools in power gui to excel. I have 4 input signal available and 3 signal number (i.e. it is a 3 phase sytem with 4 different currents). I tried to export it to MATLAB ...
change,butitiswhitenoise,andoccursinallfrequencybinsoftheFFT.Wenowhave100timesas many frequency bins as before, so we have to expect that the signal power within one frequency bin is diminished by a factor of 100, or 20 dB. Figure 1 shows these two simulations next to each other. The ...
how to create model in Simulink of MATLAB code? i was stuck in create FFT in Simulink and plotting frequency domain in Simulink.You can directly use a "MATLAB Function" block where you can encompass the FFT logic into a function and plot the dat...
of a shifted time series and my graphs are not appearing as I expect them to:To plot the FFT of a shifted time series and understand its behavior, it is important to ensure that the time and frequency domains are correctly handled. The current code has a few issues that need to be ...
Open in MATLAB Online Hi Riya, You can generate random values with rand function and perform DFT with fft function. Simply, ThemeCopy x = rand(12,1); y = fft(x); For more datils on random number generations, look here. Hope this helps. Regard...
Doing a project on the Power quality improvement. Got stuck while plotting the above graph. The Matlab help states I can use the Spectrum Analyzer to do that but idk whats wrong with my copy of matlab that there is no such thing as Distortion Mea...
Open in MATLAB Online I am having difficulty in finding a high-resolution frequency spectrum even though I have a pretty large number of time domain data samples (1999999 data points). The fundamental frequency peak in FFT is with a resolution of 50 Hz when I use fft(). I had ...
Line spread function(LSF) is the derivative of the linear edge profile. MTF is the fast fourier transform (FFT) of the LSF. When LSF is selected, LSF variance (σ2), which is proportional to theDxO blur unit, is displayed. Edge pixel profileis proportional to the edge profile in pixels...
