I think it'll be useful.
Dear Hayfa I suggest some advice to you
Are you be familar with wavelte Transform?
Did you read this tutorial:
**broken link removed**
Did you read the Help of Wavelet Toolbox?
empirical mode decomposition, signal detection
if you have IEEE account you can search EMD and find many useful paper such as:
1.Optimal and Bidirectional optimal Empirical Mode Decomposition
Binwei Weng; Barner, K.E.;
Acoustics, Speech and Signal Processing, 2007. ICASSP 2007. IEEE...
empirical modal decomposition
Empirical mode decomposition (EMD) is a signal processing technique for analysing any signal to a number of amplitude and frequency modulated functions. Although it was discovered about 10 years ago, it has recently received much attention due to its successful...
Dear Hayfa
I've replied your question
if you want to compress ECG signal with Wavelet Transform You should be familar
with this Transform.this link will help you:
**broken link removed**
also you can read may book abuout wavelet theory to be familar with this transform.you can search on this...
how do you want to perform your filter?
simulink or making physically?
this link give basic information about HPF:
https://en.wikipedia.org/wiki/High-pass_filter
Are you famillar with Wavelet Transform?
In Wavdec syntax this command decompose the signal and use downsampling method So the sampling frequency will be change but i want to calcilate it exactly.
Could you help me?
What is the format of the signal files?
Many formats are supported. Most signal files are written in "format 212", in which two 12-bit samples are bit-packed into three 8-bit bytes. See signal(5) in the WFDB Applications Guide for details on format 212 and on the other supported formats.

Dear Hayfa
dont be worried
i''ll explain it for you step by step but you should do this steps in matlab and say
your result.
you run this file in matlab
PhysioNet_ECG_Exporter_2.m
right?
and in matlab command appear this questions.
Path Where Data Is Stored, Else Leave Blank =

hi
this is a refinable equation
φ(x)=2*∑h(k) φ(2x-k)
I have the h(n) sequence and I want to compute φ(x)
h(k)=[ -0.1294 0.2241 0.8365 0.4830] it is a low pass filter and the φ(x) is scaling function.
the index of this seris is from k=0 to k=N-1
more accurate I need matlab code to...
Re: Need help...urgent
QR factorization or QR decomposition is a decomposition of the matrix into an orthogonal and a triangular matrix.
visit this link:
https://en.wikipedia.org/wiki/QR_factorization
I think if you read matlab tutorial help about wavelet toolbox it may more help you.
it's too large and I can't upload this now BCZ I'm busy.So you can search and if you dont't get this file i'll upload it.
