Open in MATLAB Online Ais a vector, and I want to take the sum of the exponential of-t/A_iover each element ofA, then take the FFT. I wasn't sure what range to take for t, though it should go over several orders of magnitude. Would there be a better way to do this than just...

I want to test my FFT design in VHDL. For this, I plan to get the outputs from VHDL simulations in a file and feed them as an input to MATLAB FFT code. Then take the output from MATLAB as reference and use it as a reference for my VHDL ...

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...
matlab fft frequency scale Hmm ok i got it. So if I have to use a higher frequency for carrier such as 10kHz then my sampling frequency also should be in range greater than 10k rite? Added after 1 minutes: When would a frequency domain aliasing take place? Oct 15,...
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 ...
I want use fft in matlab to compute the frequency of my licking signal. What all I have is the time when the rat has licked sugar water. Can somebody please tell me how I can compute the frequency of my signal. 0 Comments Sign in to comment. Sign in to answer this question....
The fundamental frequency peak in FFT is with a resolution of 50 Hz when I use fft(). I had also put this post here with the screenshots, code, and data. I am thinking of using pspectrum() or zoomFFT(). The latter seems to be more relevant to me. But after creating ...
I am doing a sensor project, and I need to measure output signal from the sensors. Theoretically speaking, output signal should be sine wave.However, sensor itself has got sine-wave-like noise. Therefore the supercomposition of two waves forms weired output signal. ...
