This article describes methods of speech processing especially for cellular systems and internet voice communication.Oneof the most popular formats used for speech processing is PCM (Pulse Code Modulation) format, which has a high processing accuracy.However,long words and timeconsuming multiply operationsrestricts the usage of PCM codes.More advantageous to that,DPCM (Differential Pulse Code Modulation), which has a similar resolution as PCM but operates on shorter word lengths was developed DPCM uses delta modulation (DM) codes to obtain bett ....etc

matlab code for super resolution of an image using discrete wavelet transform
Abstract
Super resolution is very useful and interesting area of research in image processing applications based on wavelet transform. Many algorithms have been developed by researchers based on Projection Onto Convex Set (POCS), Maximum-aposteriori (MAP) and Maximum Likelihood (ML). In this paper, we propose super resolution algorithm based on Stationary Wavelet Transform (SWT) and Discrete Wavelet Transform (DWT). Single frame super resolution can be achieved by u ....etc

The Discrete Cosine Transform
Introduction
Transform coding constitutes an integral component of contemporary image/video processing
applications. Transform coding relies on the premise that pixels in an image exhibit a certain
level of correlation with their neighboring pixels. Similarly in a video transmission system,
adjacent pixels in consecutive frames2 show very high correlation. Consequently, these
correlations can be exploited to predict the value of a pixel from its r ....etc

A FAST PIPELINED IMPLEMENTATION OF TWO DIMENSIONAL INVERSE DISCRETE COSINE TRANSFORMS
Abstract:- The inverse discrete cosine transform (IDCT) is a significant component in today s JPEG and MPEG decoders. Of all the stages in the decoding process of a JPEG file, the IDCT is the most computationally intensive. Hence, we require fast and efficient implementations, either in software or hardware. Numerous individual designs for computing the ID-IDCT have been proposed. Our 2D-IDCT incorporates two of our ID-IDCT cores and a transpose network to ....etc

AUTOMATIC DETECTION OF ARRHYTHMIA IN ECG SIGNAL USING DISCRETE COSINE TRANSFORM
ABSTRACT
The Electrocardiogram (ECG) is the bioelectrical activity of the signal of the heart which represents the cyclic rhythm of contraction and relaxation of the heart muscles.
An arrhythmia is an irregularity with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.
The P,Q,R,S and T waves of the ECG signal contains all important features, t ....etc
