However, aperiodic discrete-time signals require a continuum of complex exponentials to represent them. Thus, the Fourier transform of a discrete-time signal is a continuous function of frequency.

Figure 2 – Square wave fixer-upper circuit. It is possible to see the individual frequency components predicted by the Fourier series. Most modern scopes can compute the Fourier transform of a signal, ...

According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs in the HARMONIC SERIES, where the Fourier coefficients give the AMPLITUDE ... for transferring a time-domain ...

The book starts with a discussion of statistical correlation, before introducing Fourier series and building to the fast Fourier transform (FFT) and related periodogram techniques. The theory is ...

The more general form of transferring the frequency domain to the time domain is termed the inverse Fourier transform. See: COMPLEX TONE, FOURIER THEOREM, HARMONIC SERIES, SINE WAVE. Compare: GRANULAR ...

We’ve seen many graphical and animated explainers for the Fourier series. We suppose it is because it is so much fun to create the little moving pictures, and, as a bonus, it really helps ...
