Denoising of ECG signal - Paper Review

-
The paper concludes the work done so far the denoising of ECG signal and authentication. The cardiac muscles is generating the cardiac signals that representing by electrocardiogram. An ECG signal is noise free and it is used to analysis and identifying the person. It is necessary to denoised the loud signal using various techniques like wavelet transform, Kalman Filter, FIR filter, etc. noisy signals are decomposed and noisy components appear in coefficients of detail. The threshold applies to corrupt bands. Using inverse technique the detailed sub-bands are reconstructed. The feature is extracted from denoising of ECG signals and classified the persons. Various classifiers are used and compared to existing methods. K-NN, ANN, SVM are the common techniques of classification used. The future work mainly concentrates on developing an algorithm for de-noising and accurate authentication.

Exp- 4 Filtering of Long Data Sequence using Overlap Add and Overlap Save method

-
Overlap Add and Overlap Save method are used for filtering long data sequences. Such a long data sequence would need a very high order FFT- which is not feasible and the process can only start after we've obtained the entire data sequence which leads to a delay. The long data sequence is broken into smaller parts and performed FFT analysis. It is then fitted with one another, the overlapped portion is discarded in Overlap Save Method whereas it is added in OAM to get required output sequence.

Exp-2 Discrete Fourier Transform

This practical really helped me understand DFT in a greater depth. It helped me connect the knowledge sir taught in the class, and aquire a greater understanding. In  mathematics , the  discrete Fourier transform  ( DFT ) converts a finite sequence of equally-spaced  samples  of a  function  into a same-length sequence of equally-spaced samples of the  discrete-time Fourier transform  (DTFT), which is a  complex-valued  function of frequency. The interval at which the DTFT is sampled is the reciprocal of the duration of the input sequence. To understand DFT better, we've performed discrete Fourier transform of a 4 point sequence by coding it. What I learned in that experiment is: 1) Results by DFT are always periodic about the number of input values. 2)The spectrum is discrete from o to pi. 3)Upon zero-padding the input signal, the length of the input signal increased- which increases the frequency spacing. 4)As frequ...

Exp-3 Fast Fourier Transform

Image
Fast Fourier Transform(FFT) A   Fast Fourier transform  ( FFT ) is an algorithm that samples a signal over a period of time (or space) and divides it into its frequency components. FFT is manually verified and performed using flowgraphs. FFT is much faster than DFT and more efficient as it requires less number of real and complex additions and multiplication. The computation is considerably reduced from M2N2 to MNlogMlogN
