Introduction

Wavelet transforms have been one of the important signal processing developments in the last decade, especially for the applications such as time-frequency analysis, data compression, segmentation and vision. During the past decade, several efficient implementations of wavelet transforms have been derived. The theory of wavelets has roots in quantum mechanics and the theory of functions though a unifying framework is a recent occurrence. Wavelet analysis is performed using a prototype function called a wavelet.

ABSTRACT
Mathematical transformations are applied to signals to obtain further information from the signal that is not readily available in the raw signal. By applying the various transformations available today, the frequency information in these signals is obtained. There are many transforms that are used quite often by engineers and mathematician s. Hilbert transforms, short-time Fourier transforms, Radon transform, and the Wavelet transform constitute only a small portion of a huge list of transforms ....etc

LED BRIGHTNESS CONTROLLING USING SERIAL PORT



Interfacing with pc

Interfacing is done using RS232 DS-9 port which is connected to pc & microcontroller.
On port 3,at p3.0 & p3.1 the input signal is received.
TXD,RXD pins are also used in interfacing.

Sending signals from pc

To send signals from pc we need to make a software using vb .net .This signals will vary from 0 to 255.As per this signals the PWM will vary by duty cycle in microcontroller, resulting in a c ....etc

ECG Analysis using Wavelet Transforms



Electrocardiograph

Electrical activity of the heart, condition of the heart muscle.
Waves are inscribed on ECG during myocardial depolarization and repolarization.
Usually time-domain ECG signals are used.
New computerized ECG recorders utilize frequency information to detect pathological condition.
ECG consists of P-wave, QRS-complex, the T-wave and U-wave.
P-wave-depolarization of atria.
QRS-complex-depolarization of ventricles.
T-wave-repolarization of ven ....etc

SELECTION OF BIORTHOGONAL FILTERS FOR IMAGE
COMPRESSION OF MR IMAGES USING WAVELET PACKETS

The need for application of image compression algorithms to medical arises as a result of the immense amount of data produced.The basic idea behind most of the lossy compression algorithms is to transform the image
and to project it on an orthogonal function basis in order to distribute the energy of the signal among these
decorrelated components. Fourier, Cosine and
Karhunen-Lo ve are the available algorithms. JPEG is based on this transf ....etc

FAST HADAMARD TRANSFORMS

Abstract:- The Hadamard transform (also known as the Walsh-Hadamard transform, Hadamard-Rademacher-Walsh transform, Walsh transform, or Walsh-Fourier transform) is an example of a generalized class of Fourier transforms. The Hadamard transform can be regarded as being built out of size-2 discrete Fourier transforms (DFTs), and is in fact equivalent to a multidimensional DFT of size. It decomposes an arbitrary input vector into a superposition of Walsh functions. ....etc
