Concepts for the analysis of continuous and discrete-time systems including convolution, impulse and pulse responses, step responses, continuous and discrete Fourier transforms, frequency responses, Laplace and z-transforms. From continuous to discrete signals and back via sampling and the Nyquist sampling theorem. Signal processing in mechanical systems including chattering phenomenon analysis. Introduction to communication systems including amplitude and pulse amplitude modulation, demodulation, and frequency and time-division multiplexing. Introduction to feedback control including concepts of stability and robustness. Lecture notes available for students of this subjects. Exercises in computer classroom using Mathlab and Simulink.
