Adam2015년 6월 8일 Have you looked at the fft help in the Matlab documentation? There are a number of examples in there for doing fft analysis. 댓글을 달려면 로그인하십시오. 태그 fft spectrum subsy... fft...
Matlab uses the FFT to find the frequency components of a discrete signal. The following is an example of how to use the FFT to analyze an audio file in Matlab. The file in this example is the recording of a tuning fork resonating at the note A4. This shows how the Fourier transform ...

i am conducting an experiment , and data collected in the Timme vs displacement format. I convert it into frequency domain using fft. Although i am getting low and high frequencies. "But i want only the highfrequency and remove the low ones. What...
Open in MATLAB Online Hello, Please can you help me saving the result of the Fast Fourier Transform of an image so I can reuse it to draw the bessel function? My code below, gives this error : In an assignment A(:) = B, the number of elements in A and B must be the...
given non explicitly ,and the other is two Dirac functions,using MATLAB - I need the plot .
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 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 ...
3. I do an IFFT of my response and plot them against time (here time is the inverse of the freq points). 2. Then I apply time gate and do FFt back to freq domain and I lose the responses of outside the time gate in freq domain. My knowledge is coming from this document: Just...
how to do convolution without commandsThis is a little more complex than necessary - you don't need the first loop that reflects A, just change the index computation in the second loop to reflect the mathematical definition of convolution.You...
