Key considerations for sample prep for DRIFTS experimentPlay Video Credit: Specac Ltd DRIFTS is routinely used in quality control applications, materials characterization, and catalytic studies in ...

Fast Fourier Transform Equation (9) can be written in the matrix formalism. Precisely, of the product rows by columns of a square matrix of order N and a column vector of N rows. The calculation of ...

Fourier transform The presence of the singularity at t = 0 of any unitary impulse should not scare us because the impulse is in any case zero at infinity so we expect a convergence of the Fourier ...

This paper proposes the simulation parameters of the fast Fourier transform (FFT) for the 3-dimensional (3D) split step parabolic equation (SSPE) and the mirror Kirchhoff approximation (MKA). The SSPE ...

Fourier transforms are one of the most important algorithms in math, and help our electronics handle visual and audio signals in a sophisticated way.
