Sta-called analog computers use circuits to solve mathematical problems, particularly when they involve differential equations. Suppose we are given the following differential equation to solve. d t) dt + aye) = me) In this equation, a is a constant. 1. When the input is a unit step the output is given by (X(t)=U(t)) What is the total energy expended by the input? y(t) = (1 e"\"")u(t)
