3.4 : The Sinusoid

Welcome to Week 3 Lecture 4 of the course "Electronic Systems Thinking", taught by Profs. Sankaran Aniruddhan, Boby George, and Janakiraman Viraraghavan. Full Course: https://study.iitm.ac.in/es/course_pa... Video Overview This lecture introduces time varying signals with a focus on the sinusoidal signal as a cornerstone of electrical engineering. We explain the key properties of sinusoidal signals including amplitude, frequency, and phase, and connect them to real world applications such as generators, simple harmonic motion, and musical instruments. The lecture also shows how alternating current sources applied to resistors lead to instantaneous and average power calculations, and concludes with an introduction to root mean square voltages.
