The Hilbert transform Mathias Johansson Master Thesis Mathematics/Applied Mathematics Supervisor: BÄrje Nilsson‚ VÄxjÄ University. o a o Examiner: BÄrje Nilsson‚ VÄxjÄ University. o a o Abstract The information about the Hilbert transform is often scattered in books about signal processing. Their authors frequently use mathematical formulas without explaining them thoroughly to the reader. The purpose of this report is to make a more stringent presentation of the Hilbert transform but still

Research has shown that Manta Rays and Devil Rays are cousins but are different types of marine life. Although they are cousins‚ they are different. They have different body types‚ different habitats and different intelligence levels. If you ever see a manta ray or a devil ray‚ they look very similar. It may not look like they have different bodies but they do. A manta ray can grow to a size of 7m (23ft) and weigh up to 3‚600 pounds. It has 18 rows of teeth on their lower jaw. Their eyes are on

Science & Technology in The 1950s Easier Business Dealings Ever since the credit card was invented‚ the transactions were much easier compared to the pass as a swipe of the card would settle up the large payment instead of bringing large amount of cash which would have risk of getting rob.

In 1950‚ the concept of using the same card for various payments was found out by Ralph Schneider

established the basic specifications for a next generation large capacity optical disc video recording format called "Blu-ray Disc". The Blu-ray Disc enables the recording‚ rewriting and play back of up to 27 gigabytes (GB) of data on a single sided single layer 12cm CD/DVD size disc using a 405nm blue-violet laser. By employing a short wavelength blue violet laser‚ the Blu-ray Disc successfully minimizes its beam spot size by making the numerical aperture (NA) on a field lens that converges the

Fractional Fourier Transform Adhemar Bultheel and H´ctor E. Mart´ e ınez Sulbaran 1 Dept. of Computer Science‚ Celestijnenlaan 200A‚ B-3001 Leuven Abstract In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that filters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform algorithm
