Example 8.21: A causal LTI system is described by the difference equation y(n) - ay(n - 1) = bx(n) + k(n-1) where a is real and its magnitude is less than 1. Find the value of b (b + a) such that the frequency response of the system satisfies |H(ejw)] = 1 for all w, an all pass system and the magnitude is constant independent of its frequency -
