Dear jtlindgren ,
This scenario i am applying at every decomposition level of a dwt to find the spectral power of the signal .
spectral analysis - squaring it -spectrum average -csv (process in Matlab for the computation of statistical values) .Is it the correct sequence ?
Thanks
Adeel

Re: Spectral analysis box query about amplitude and power
Hi , If I will square all my spectrum amplitude values and then use the Spectrum Average box to give me the spectrum power indicator that I need.Is it true to square the spectrum amplitude to find the power and if so then what will be the unit of it ?kindly tell me about its graphical representation...

Re: PSD display error
Dear jtlindgren,
Thanks for the fast reply .I am using DWT as a frequency classifier .I want to display the power spectrum of all the frequency band .For that I want to apply fft spectrum at each coefficient of the wavelet to find the power of the specific band.
Thanks

PSD display error & wavelet decomposition
Dear all,
I am using power spectrum display for the analysis of alpha and beta rhythm .Instead of using filters power spectrum will display the strength of whole signal e.g.if i display for only alpha it will display other rhythm as well .Please help me in this regard .
Thanks
Adeel

Visualization of eeg in real time
Is openvibe suitable for visualization of eeg in real time?Kindly guide me in this regard as i am at the beginning stage of this project .Your suggestion will be highly appreciated in this regard
