This course introduces the mathematical framework for the description, analysis and processing of signals such as music, speech and images. Main topics covered include signal representations in different bases; continuous-time signal sampling; and signal processing by linear and time-invariant systems.
Learning Outcomes1Describe and analyze continuous-time and discrete-time signals in different bases.
2Understand the relation between a continuous-time signal and a sampling of that signal, including methods to reconstruct a continuous-time signal from its samples and applicability conditions.
3Describe and analyze the properties of continuous-time and discrete time systems in different bases.
4Construct linear and time-invariant systems to process continuous-time and discrete-time signals.
