Define orthogonal signal space and bring out clearly its application in representing a signal.

Answer»

Any TWO signals say 500Hz and 1000Hz (On a constraint that both frequencies are MULTIPLE of its fundamental here lets say 100Hz) ,when both are mixed the RESULTANT wave obtained is said to be orthogonal. Meaning: Orthogonalmeans having exactly 90 DEGREE shift between those 2 signals.
