Laplace Transform

OBJECTIVES

In this chapter you will learn about:

• Define the Laplace transform of a function
• Use the table of Laplace transforms
• Use partial fractions to deduce inverse Laplace transforms
• Deduce expressions for component and circuit impedances
• Deduce Kirchhoff’s law equations in the s plane for determining the response of networks given initial conditions
• Predict the circuit response of a network
• Classify poles and zeros
• Analyse a circuit with Laplace transform
