The document provides a course plan and evaluation plan for a Linear Systems & Signals course. The course is a 3 credit, 3 lecture hour course taught in the Electronics and Communication Engineering department. The course objectives are to analyze electrical circuits, signals, and systems in both the time and transform domains. The course will cover topics including circuit analysis, time domain analysis of linear systems, transform domain analysis using Laplace transforms, and frequency domain analysis of continuous time signals and systems. Students will be evaluated based on a mid semester exam (25%), assignments and quizzes (25%), and an end semester exam (50%).
