Description: A system is a set of interconnected devices that serve a function. An information system is a system whose function is to take information generated by a source and deliver that information in a reliable manner to a destination. The transmitted information is modeled as a signal, namely a function mapping time instants onto the values that the signal takes. This course introduces mathematical methods used in signal processing and demonstrates how those methods are used in information systems. Course topics include circuit analysis, time-domain analysis of continuous-time systems, Fourier series, continuous time Fourier Transforms, Sampling, and Discrete-time Fourier Transform methods for signals and systems. These methods will be demonstrated
