natural basis for CONTINOUS SIGNAL
can some one plz tell me what will be the natural basis for continous signal as generally we used to have [1 0 0 ]
[0 1 0 ]
[0 0 1 ]
in 3d discrete signals it would be great if some one tell about 3 or 4 orthonormal possible basis for continous signal represenattion.
 

This is my interpretation. just tell me whether it is right..

you all agree that we use weighted summation of these basis functions to represent our signal (or vector)..

Now consider a continious but periodic signal. It can be decomposed into 'N' fourier coeffecients. So the basis functions we are using are 'N' orthogonal sinusoids.
If the cont signal is aperiodic then we need infinite number of sinusoids. So for continious signals the choice for the number of basis functions depends on minimising the error between the signal and its representation

Am I right??

well well good try infact i must say U HAV visualized the fourier series /transform to all readers ,u r absolutly right in what u r saying
BUT
brother my problem is some what different i want certain basis other then sine/cosine to represent my signal in signal space, WHAT i asked in the post was a curious question that is there any basis like natural basis in finite domain ,but now i am thinking that the best possible basis is infact of fourier domain basis,CAN ANY BODY HAV ANY IDEA OF OTHER BASIS WE CAN CALL NATURAL BASIS OF CONTINOUS DOMAIN
