Yeah! if it is AC excitation obviously there will be eddy currents irrespective of it motion or speed!!
How about, when its rotating in constant DC excited magnetic field?? Eddy currents are generated in this case?
Thank for your reply! :-D
I have a doubt that, whether eddy currents exists in a rotor which is rotating in a DC magnetic field or not?
Can we create a strong pulling force on a rotor in a particular direction by using AC magnetic field??
i am attaching a figure, please check it...
How to calculate Eddy current force generated in a rotating ferromagnetic material in D.C. magnetic field which exerting a pulling force on rotor about 2000 N.
go for crosswavelet transform of the normal ecg and disease ecg. then you can easily extract the features from it. then you can go for classification easily...
code for XWT available here.
**broken link removed**
search ieee website with key words "feature extraction cross wavelet transform"...
I am getting the cross wavelet spectrum of two signals as shown. in that spectrum some significant black noise is coming in the upper half. that is shown in box. any body please help me how to remove this black noise.......
you can use EMD technique on it for feature extraction, the matlab code is available on the net, after that u can implement HHT on it further classification
I Need help for matlab code for marginal hilbert spectrum
Any body send me the matlab code for 'marginal hilbert spectrum'. It is needed for my academic project.
Please help me....
Thank you.
you can go through EMPIRICAL MODE DECOMPOSITION TECHNIQUE OR INDEPENDENT COMPONENT ANALYSIS..these are signal processing techniques and those MATLAB codes also available in the NET.
thank you for your reply, but i want know how to calculate value of the signal energy, from its FFT, the area under the curve is equal to energy of the signal? below code is correct to calculate energy of signal?
fs = 10000; % Sample frequency (Hz)

how to find the no. of zero crossings of a random signal in matlab.
i am using this code, but i am not getting the exact answer,
function zc=zcr(sig,N)
clear all;
fid=fopen('C:\Documents and Settings\Measurement lab\Desktop\imf1.txt');
data=fread(fid,1000,'bit4');
plot(data(1:100));
