Web11 Dec 2024 · Square waves are discontinuous functions. I'm wondering if there's a continuous function that "sounds the same as" a square wave, in the sense that it has components with the same amplitude and frequency as the series above, but with different phases. Do there exist a n ∈ R such that ∑ n ∈ N n odd 1 n sin ( n t + a n) WebThe DFT is in general defined for complex inputs and outputs, and a single-frequency component at linear frequency \(f\) is represented by a complex exponential \(a_m = \exp\{2\pi i\,f m\Delta t\}\), where \(\Delta t\) is the sampling interval.. The values in the result follow so-called “standard” order: If A = fft(a, n), then A[0] contains the zero …

WebThe DFT is the right tool for the job of calculating up to numerical precision the coefficients of the Fourier series of a function, defined as an analytic expression of the argument or as a numerical interpolating function over some discrete points. WebThe Discrete Fourier Transform (DFT) is used to determine the frequency content of signals and the Fast Fourier Transform (FFT) is an efficient method for calculating the DFT. Fourier analysis is fundamentally a method: To express a function as a sum of periodic components. To recover the function from those components.
