This course covers continuous time
signal models, convolution, and superposition integral and impulse
response. Students also study Fourier series and periodic signals,
Parseval's theorem, energy spectral density, Fourier transform and
filters, discrete time signals, difference equations, discrete
Fourier transform, and discrete convolution.
Signals is an introductory course that
develops mathematical techniques for modeling continuous and
discrete signals and linear systems. Analog and digital signal
processing theory is taught simultaneously to emphasize the power
of these mathematical abstractions. Classroom lectures are
supplemented by computer simulations that reinforce significant
concepts. Topics covered in this course include basic linear
system theory, time domain methods such as convolution, frequency
domain methods such as the Fourier transform, the Z-transform, and
filter design and implementation. This is a four credit hour
lecture course that includes three hours of lecture and one credit
hour of recitation.
