Linear transforms — like a Fourier transform — are a key math ... The technique doesn’t use any conventional processing elements and, instead, relies on diffractive surfaces.

He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video after the break shows that the results are quite pleasing, with just a bit ...

SINCE the publication of Prof. Zygmund's “Trigonometric Series” in 1935, there has been considerable demand for another book dealing with trigonometric integrals. Prof. Titchmarsh's book meets ...

A more general form of analysis for transferring a time-domain signal to the frequency domain is called the Fourier transform. Compare: FOURIER SYNTHESIS, HELMHOLTZ RESONATOR, LAW OF SUPERPOSITION, ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
