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, ...

If you've spent any time on the Internet, at some point you've heard the phrase "Fourier transform." It's it's a mathematical discovery that's baked into ...

Here’s a really quick video which takes a different approach to understanding the Fourier Series than we’re used to. If you’re a regular reader we’re sure you’ve heard… ...

The construction of a PERIODIC signal on the basis of Fourier coefficients which give the AMPLITUDE and PHASE angle of each component sine wave HARMONIC.These coefficients are obtained through FOURIER ...

The Laplace transform is less familiar, even though it is a generalization of the Fourier transform. [Steve Bruntun] has a good explanation of the math behind the Laplace transform in a recent ...

The principle of the Fourier transform, which dates back to the 19th century, is that any signal, such as a sound recording, can be represented as the sum of a collection of sine and cosine waves ...

A sine wave is an S-shaped waveform defined by the mathematical function y = sin x. It is depicted graphically as two semi-circular curves that alternate above and below a center line.

Stationary-wave integrated Fourier-transform spectrometry (SWIFTS)—an approach based on direct intensity detection of a standing wave resulting from either reflection ...
