This, in combination with the result from the Initial Value Theorem, tells us much about this particular signal. If this were the output of a circuit, we could now conclude that immediatel y after „switch on,‟ or when time is just after zero, it has a value of Also, we know that the response settles in the long term to a stable value of ; this is the steady- state response. We will see the full importance of these conclusions when we start to examine circuit initial and steady-state behavior in more detail. As with the table of common Laplace Transforms, we can also summarize the above theorems into a quick reference table. It will be available on any test or exam that requires you to directly calculate a Laplace Transform. Note that the last entry was not discussed above; we will cover this later for transfer functions. Required Reading: Table of Laplace Properties
