I2

So-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.
dy(t)
dt
+ ay(t) = x(t)
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-(at))u(t)
