WebbExponential Signal. Exponential signal is in the form of x (t) = e α t. The shape of exponential can be defined by α. Case i: if α = 0 → x (t) = e 0 = 1. Case ii: if α < 0 i.e. -ve then x (t) = e − α t. The shape is called decaying exponential. Case iii: if α > 0 i.e. +ve then x (t) = e α t. The shape is called raising exponential.
