This lecture introduces transfer functions as a tool for analyzing feedback systems using frequency response and Bode plots. The lecture uses the example of a spring, mass, damper system to show how transfer functions can be used to compute the frequency response of an interconnected system of components. We also define poles and zeros and indicate how they affect the frequency response of a system. Finally, we introduce the general computations of block diagram algebra.
This lecture gives a brief introduction to the Laplace transfrom and describes how it relates to the transfer function for an input/output system.
Friday: Bode plots (Notes, MP3)
This lecture focuses on Bode plots, including how to recognize key features of the plots and how to sketch them by hand.

This homework set covers basic transfer function concepts. The conceptual problems show how to create a frequency response for a complex system of components using MATLAB. The analytical problems cover basic anaytical concepts in transfer functions.
