This is an undergraduate level foundation course intended for a wide variety of disciplines in engineering and science: and a part of this syllabus is typically offered at present as a core course in the second/ third year of a typical undergraduate programme in Electrical Engineering; and even in Electronic Science/ Instrumentation/ Information Technology in some places. As such, the course is not restricted to Electrical Engineering majors. It is used by many disciplines in various contexts; and they are welcome to/ encouraged to take it if they choose. Broad aims of the course: 1. To introduce the student to the idea of signal and system analysis and characterization. 2. To provide a foundation to numerous other courses that deal with signal and system concepts directly or indirectly: communication, control, instrumentation, and so on. The concepts in this course are also useful to students of disciplines other than electrical engineering; since signal and system analysis is required in many branches of engineering and science: for example, mechanical engineering, chemical engineering, aerospace engineering, biomedical engineering, data analysts. 3. To expose the student to some advanced topics in signal and system analysis: examples being statistical signal processing, time-frequency methods and wavelet analysis. Proposed syllabus for the course: 1. An introduction to signals and systems: Formalizing signals,formalizing systems: 2. Continuous time and discrete time Linear shift-invariant (LSI) systems in detail: the impulse response and step response, convolution, input-output behaviour with aperiodic convergent inputs, cascade interconnections.

Generalization of Parseval’s Theorem. 5. The z-Transform for discrete time signals and systems: eigenfunctions, region of convergence, system functions, poles and zeros of systems and sequences, z-domain analysis.
