Analysis of continuous- and discrete-time linear systems based upon convolution integral, Fourier series and Fourier transforms, linear differential/difference equations, Laplace transform, and z-transform. Topics include pulse/impulse response, frequency response, transfer functions, sampling, and example applications in communications and control.
