The double-density DWT is an improvement upon the critically sampled DWT with important additional properties: (1) It employs one scaling function and two distinct wavelets, which are designed to be offset from one another by one half, (2) The double-density DWT is overcomplete by a factor of two, and (3) It is nearly shift-invariant. In two dimensions, this transform outperforms the standard DWT in terms of denoising however, there is room for improvement because not all of the wavelets are directional. That is, although the double-density DWT utilizes more wavelets, some lack a dominant spatial orientation, which prevents them from being able to isolate those directions.

This guide is an attempt to compile a lot of that information in here and dummy it down. Perhaps it s a fairly common show, perhaps not. It might have even been a show that you taped. Whatever the case, you want to share it with others bur aren t quite sure how. This guide should be your answer. This guide is geared towards posting a show at SharingTheGroove.org. The instructions contained within are for that site. Other sites hosting BT shows may have slightly different procedures for getting the torrent to them. However, torrent creation will be the same. While this guide is being written with audio concerts in mind, the same holds true for the video section of The Groove.

SPREAD SPECTRUM MODULATION TECHNIQUES -spread spectrum - those modulation methods that are producing a signal whose spectrum is more wider than of the data signal, the occupied frequency band being independent by the signal of data band. -The signals with spread spectrum of direct sequence type BPSK (BPSK-DS-SS) -The signals with spread spectrum of direct sequence type QPSK – DS–SS - Frequency hopping spread spectrum signals (FH-SS)

This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file. Compression ratio is fixed for IMA-ADPCM, being 4:1. PLEASE NOTICE THAT THIS CORE IS LICENSED UNDER http://creativecommons.org/licenses/by-nc-sa/3.0/ (Creative Commons Attribution-Noncommercial-Share Alike 3.0 Unported).

GNU_Radio GNU radio is a free/open-source software toolkit for and the content is controlled by a handful of organizations. Cell building software radios, in which software defines the phones are a great convenience, but the features your phone transmitted waveforms and demodulates the received supports are determined by the operator s interests, not yours. waveforms. Software radio is the technique of getting code A centralized system limits the rate of innovation. Instead of as close to the antenna as possible. It turns radio hardware cell phones being second-class citizens, usable only if problems into software problems.

Imagine that you are a web developer (which is probably not a stretch if you are reading this book) and you are being encouraged to add some Ajax features to a site you’re working on. Maybe the originator of this request is your boss or your boss’s boss, who is not even sure what Ajax is, let alone what kinds of features might be useful.And maybe you’re not sure yourself. Imagine that your prior experience has mostly been on the server-side, developing in Java or some other server-side technology, and your experience with HTML and JavaScript has been fairly limited.This is the scenario we will explore over the next several chapters as you are introduced to the Dojo Toolkit.

Normally a list view is updated by a user directly by selecting a list view item and then editing or deleting it. New items are usually added at the bottom of the list. This works fine since the user knows which items have been changed or deleted and where the new items will pop up. A drawback of it is that, if the list is sorted, then new items will not be displayed in a sorted way, instead they will be listed in the order of being created.

This application note considers the design of frequency- selective filters, which modify the frequency content and phase of input signals according to some specification. Two classes of frequency-selective digital filters are considered: infinite impulse response (IIR) and finite impulse response (FIR) filters. The design process consists of determining the coefficients of the IIR or FIR filters, which results in the desired magnitude and phase response being closely approximated.
