Principles of Signals and Systems

This 76-lecture NPTEL course from IIT Kanpur builds the principles of signals and systems in a careful order. It begins by classifying continuous and discrete-time signals, then separates analog from digital and energy from power signals before any system is analyzed.

Systems and their properties

The course looks at memory and causality, then the properties of linear systems. A long run of lectures on LTI systems, in both continuous and discrete time, follows, with example problems placed between the theory to test each idea.

Points worth noting

• Example-problem lectures appear several times, so the course stays practical as it goes.
• Discrete-time LTI systems are given their own lecture, which helps learners who will move into digital signal processing.
• The early classification lectures set vocabulary used throughout, so they repay a careful watch.
