The alpha beta filter equation is given by this
Xni = AXn + BXn1 Xn1 is subscript i want to figure the solution to this recurrence relation, but is it a recurrence relation? i am wondering weather alpha beta filters grow faster than exponential smoothing filters.  i said it is a 1st order equation where Xn = C1 (B/1A)^n so alpha beta filtering grow polynomial But i am not quite sure to find the grow rate of the exponential filtering equation

sorry this is wrong, the alpha beta filter equation is not a recurrence relation..
