This course consists of 25 video lectures given by Professor Dennis Freeman.
It covers the fundamentals of signal and system analysis, focusing on representations of discretetime and continuoustime signals (singularity functions, complex exponentials and geometrics, Fourier representations, Laplace and Z transforms, sampling) and representations of linear, timeinvariant systems (difference and differential equations, block diagrams, system functions, poles and zeros, convolution, impulse and step responses, frequency responses).
Applications are drawn broadly from engineering and physics, including feedback and control, communications, and signal processing. (from ocw.mit.edu)
