Figure 1 shows these two simulations next to each other. The 20 dB difference is well visible. To see this in simulation is not trivial, for two reasons: first, the FFT itself also introduces a factor N, the length of the FFT, and second, as can be seen in the left plot of Fig...
How to use fft exatly with data acquired by oscilloscopeHi all i need to use the fft on an array of 5000000 values with fs=1e7 and plot it exactly. The shape is good but i'm very confused about the normalization for the fft. Someone can help me with a good code for the plot...
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...
Open in MATLAB Online @ANAS HAMZAH, To get the very narrow bandwidth shown inthe second plot in your PDF, you need to inccrease the duration of the sample of the signal. The spacing between frequencies in the discrete Fourier transform iswhere T is the duration of the signal....
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 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 c...
The Fast Fourier Transform (FFT) is an efficient way to do the DFT, and there are many different algorithms to accomplish the 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 ...
I have S11 response from vector network analyzers (VNAs). I can use time gating directly in VNA. But I want to make a code for it matlab. Somewhere my concept of time gating is fundamentally flawed.…
