How to remove the integration constants from the integrated random signal ?

Hi All

After integrating a random signal , How do I know the integration constants like after the second integration to know the equation of the added line to the signal ?

hmm.. are you trying to compute an indefinite integral?

[farzad]

No it's a signal, with a beginning and an end. and the initial point was x0 , if it's an x,y signal where x is the horizontal axis

[Martin C.]

i.e. you want the area under some curve? then I'm not sure what is meant by integration constant...

[farzad]

I exactly mean the integral you know, the contrary of derivative. every time you integrate a function , you introduce a constant. so first integration it is A , in the second integration it is AX+B

[farzad]

dear Martin, you answer has been a question so far. have I been able to clarify my case?

[Martin C.]

let's say you integrate f(x) = x^2 from 0 to 1. the answer is 1/3. There are no constants. It sounds like you're trying to find a definite integral. there are no constants associated with definite integrals...
