I am trying to compute 2D FFT on 100 million complex data (100000x1000) and it is taking 4.6 seconds approximately, but I want to reduce time. Then I ...
I am trying to plot a fourier transform of a sign wave based on the scipy documentation Desired output I want to be getting a fourier transform ...
This code computes the DFT from time domain. Can anybody see the code below and help me to get the right answer? my problem is: when I change N value, ...
I am aiming to take the fourier transform of a distribution. It is a physics problem and I am trying to transform the function from position space to ...
I wish to load a CHC or NEF file from the SHAPE software in order to read the contours under MOMOCS and make the related analyses (Plot, PCA...) I ha ...
I am try to forecast 700 different product using autoARIMA in pmdarima package. For seasonality, Fourier Series makes it easier, because all products ...
Here is my code: and here is the error message: Does this error occur because the Fourier Sine Series I am trying to graph is piece-wise smooth? ...
Find the error as a function of n, where the error is defined as the difference between two the voltage from the Fourier series (vF (t)) and the value ...
Ok, so I have been trying to code a "naive" method to calculate the coefficients for a standard Fourier Series in complex form. I am getting very clos ...
I have a signal which is a linear combination of two frequencies and I am trying to use MATLAB to determine what frequencies the (main) signal consist ...
I want to calculate the Fourier transform of some Gaussian function. Consider the simple Gaussian g(t) = e^{-t^2}. The Fourier transform of g(t) has a ...
I am reading a book of Alex Palamides, chapter 6, Fourier transform and I am trying to compute the inverse transform of a function, but when I write t ...
I am trying to determine the approximation of the following function as a ctfs: x(t) = exp(-7|t|)*cos(10*pi*t) for -0.5 <= t < 0.5 I was told ...
After computing the Fourier coefficients of my function, I'd like to plot the first terms of the serie. However, I can't get the correct result… It's ...
I am new about these topics. I research a lot of article about this issue. There are a lot of different techniques. But I am confused, because I don't ...
I'm trying to calculate the Fourier Transform of the following Gaussian: I create a new array in the spacial frequency domain (Fourier Transform ...
My data is given by the Fourier transform of the function, where the points are distributed in a ball with uniformly distributed distances and uniform ...
I've written code for a Fourier series. This is what I have so far: Then, I've also created the following function file: The problem is that whe ...
I am dealing with stelar light curves (.fits-files containing 4000 datapoints of time vs stelar brigthness, see graphic for a few examples with differ ...
