Microsoft Office Excel contains a data analysis add-in that allows to to perform a Fourier analysis of a series of numbers. So named for the French mathematician who developed the analytic technique ...

The Fourier transform underpins so much of our technological lives, in most cases probably without our realising it. The ability to mathematically split a waveform into its frequency components and ...

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 of the Fourier Series (often ...

From the beginning of its history the Royal Society has devoted much attention to the publication of communications by its Fellows and others. Within three years from the granting of the first Charter ...

P. B. Kennedy [3] studied lacunary Fourier series whose generating functions are of bounded variation on a subinterval I of [ -π, π ] and satisfy a Lispschitz condition of order α on I. We show that ...

The Fast Fourier Transform (FFT) remains a cornerstone of digital signal processing, underpinning applications from telecommunications to medical imaging. Modern FFT processors and architectures have ...

In my seminars I often talk about the importance of understanding at least a little electromagnetics theory, even for purely firmware people. But the subject is hard to understand and sometimes harder ...
