Dear all,
I have a periodic signal, that I would like to study..However, I want to
eliminate the periodicity in it, and study the remainder of the data..In other
words , is it possible to break down a periodic signal into 2 composite signals
(one periodic and the other non-periodic) that when added produce the original
periodic signal ...In that manner i can process the non-periodic composite
signal..
Regards

Hi,
I am not exactly sure of your need. Are you planning to remove a
sinusoidal? If you don't know the periodicity or the shape of the
periodic components, you can pass thru a predictive error filter to
separate the signal components. Once the predictive error filter adapts,
it can be used to break the signal into the two components.
Hope this helps,
Lalin

If you have a signal that is periodic, then it is composed of a fundamental
frequency signal and harmonics of the fundamental. That means that all the
components are periodic, and all sums of components are periodic. I do not
think you will find a non-periodic component unless the signal itself is
non-periodic.
Does this sound right?

Dear John,
Thanks alot for your mail..The signal si periodic but does have some noise that i wanted to extract..Anyways, i found a way to do 'tidal or harmonicity' analysis..
Again thanks alot
