    pass filter
  • A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit).
    low
  • A particularly bad or difficult moment
  • in a low position; near the ground; "the branches hung low"
  • A state of depression or low spirits
  • less than normal in degree or intensity or amount; "low prices"; "the reservoir is low"
  • A low point, level or figure
  • an air mass of lower pressure; often brings precipitation; "a low moved in over night bringing sleet and snow"
    fft
  • a particularly fast and efficient computational method of performing a Fourier Transform, which is the mathematical process by which raw data is processed into a usable image.
  • A fast Fourier transform (FFT) is an efficient algorithm to compute the discrete Fourier transform (DFT) and its inverse.
  • (FFTS) Twin-to-twin transfusion syndrome (TTTS, also known as Feto-Fetal Transfusion Syndrome (FFTS) and Twin Oligohydramnios-Polyhydramnios Sequence (TOPS)) is a complication of disproportionate blood supply, resulting in high morbidity and mortality.

Understanding the FFT, Second Edition, Revised
Citrus Press is proud to announce the second edition (revised) of Andy Zonst's Understanding the FFT (publication date April 2000). This edition is much more than just a "cleanup" of the original text - two completely new chapters have been added. The first of these deals with the conventional FFT (i.e., scrambled data and bit reversal) and the second is an introduction to the mathematical procedure known as convolution. The conventional FFT offers certain advantages (primarily more efficient use of RAM, allowing larger arrays to be processed); but, beyond that, if one wants to work in this field, they need to be conversant with this "standard" technology (even if they never use it).
The chapter on convolution is perhaps even more important. This technique is such an integral part of Fourier analysis that a chapter (presenting it at the same level as the other material in the book) seemed very nearly imperative. There can be no doubt that it is a better book because of these revisions, and the claim still holds that, for anyone who wants to understand and use this tool known as the FFT, this book is the best place to start.

High-Pass Filter Destruction F/22
High-Pass Filter Destruction F/22
This is a shot at f/22, manually focused to infinity. It is a close-up of a 2700K CFL lit plastic light fixture taken with AWB. It is obvious what damage I've done to the coating thus far. I am really excited about the clean spots, because that's basically where the big scratch used to be, and now it's getting nice where all of the top coating is gone. I don;t know if it will take IR pics when I get it all polished-up, but that would be COOL!

Also SOOC. The cross-hatching on the high pass filter gives a bit of a glowy soft-focus effect with the built-in flash. This is actually one of the nicest shots I've ever taken SOOC with built-in flash!

Inside the FFT Black Box: Serial and Parallel Fast Fourier Transform Algorithms (Computational Mathematics)
Are some areas of fast Fourier transforms still unclear to you? Do the notation and vocabulary seem inconsistent? Does your knowledge of their algorithmic aspects feel incomplete? The fast Fourier transform represents one of the most important advancements in scientific and engineering computing. Until now, however, treatments have been either brief, cryptic, intimidating, or not published in the open literature. Inside the FFT Black Box brings the numerous and varied ideas together in a common notational framework, clarifying vague FFT concepts.
Examples and diagrams explain algorithms completely, with consistent notation. This approach connects the algorithms explicitly to the underlying mathematics. Reviews and explanations of FFT ideas taken from engineering, mathematics, and computer science journals teach the computational techniques relevant to FFT. Two appendices familiarize readers with the design and analysis of computer algorithms, as well.
This volume employs a unified and systematic approach to FFT. It closes the gap between brief textbook introductions and intimidating treatments in the FFT literature. Inside the FFT Black Box provides an up-to-date, self-contained guide for learning the FFT and the multitude of ideas and computing techniques it employs.
