WebJun 10, 2024 · Fourier analysis is fundamentally a method for expressing a function as a sum of periodic components, and for recovering the function from those components. When both the function and its Fourier transform are replaced with discretized counterparts, it is called the discrete Fourier transform (DFT). WebUse Fourier transforms to find the frequency components of a signal buried in noise. Specify the parameters of a signal with a sampling frequency of 1 kHz and a signal duration of 1.5 seconds. Fs = 1000; % Sampling frequency T = 1/Fs; % Sampling period L = 1500; % Length of signal t = (0:L-1)*T; % Time vector

Die Fourier-Transformation (genauer die kontinuierliche Fourier-Transformation; Aussprache: [fuʁie]) ist eine mathematische Methode aus dem Bereich der Fourier-Analyse, mit der aperiodische Signale in ein kontinuierliches Spektrum zerlegt werden. Die Funktion, die dieses Spektrum beschreibt, nennt man auch Fourier-Transformierte oder Spektralfunktion. Es handelt sich dabei um eine Integraltransformation, die nach dem Mathematiker Jean Baptiste Joseph Fo…
