MATLAB Online에서 열기 I tried to execute this code but for some reason the graph of the ifft is not a perfect sine wave. Can someone please instruct me as to what I did wrong? I got the fft code from the internet and I want to get the ifft Main Code 테마복사 fo...
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 ...

Dewesoft fft(g) (attached) vs matlab fft(g) (attached) Question #2 According to a Mechanical vibration book, I have the next equation to find the FRF. I applied this but my FRF y axis value is too high so, I don't know If I didn't applied correctly. That information ...
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 ...
But the problem is the institute where I am working does not allow to use matlab and they have python and LabVIEW, so I would like to convert the matlab code to python or someone knows how to run the matlab code in python then it also be very helpful. I have attached the main code...
given non explicitly ,and the other is two Dirac functions,using MATLAB - I need the plot .
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...
