ABSTRACT
This project designs an efficient method for ECG Signal Analysis whicg has fair accuracy and the calculation time is also less. The removal of noise is the first step to be taken. The required cardiac components should be extracted and the unwanted components must be rejected. The Empirical Mode Decomposition (EMD) method is used for achieving the Enhancement of signal. its adaptive nature is the inspiration for the use of EMD for this projec..................[:=> Show Contents <=:]

Introduction to Signals & Systems

Signals:-
A signal is a time varying physical phenomenon that can convey information. Like human voice, electrocardiogram, sinusoidal, videos etc.
There are different types of signals such as
Analog or Continuous signals
Digital /Discrete signals

DISCRETE COSINE TRANSFORM

A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies.
DCTs are important to numero..................[:=> Show Contents <=:]

ases. The ECG is a graphic record of the direction and magnitude of the electrical
activity that is generated by depolarization and repolarization of the atria and
ventricles. One cardiac cycle in an ECG signal consists of the P-QRS-T waves. Most of
the clinically useful information in the ECG is found in the intervals and amplitudes
defined by its features. The development of accurate and quick methods for
automatic ECG feature extraction is of major importance, especially for the analysis
of long recordings (Holters and ambulatory systems). In fact, beat detection is
necessary to dete..................[:=> Show Contents <=:]
