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 discrete-time and continuous-time signals (singularity functions, complex exponentials
and geometrics, Fourier representations, Laplace and Z transforms, sampling) and
representations of linear, time-invariant 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)
