3.2 : The Microphone

Welcome to Week 3 Lecture 2 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_pages/EE1101.html Video Overview In this lecture, we explore electrical transducers through the example of a microphone and a compact oscilloscope. We observe time varying waveforms produced by voice and show how amplitude relates to loudness and frequency to pitch. You will see how a microphone converts sound into electrical signals, learn about the concept of DC offset, and understand the role of sinusoidal signals in electrical engineering. We also highlight the use of miniaturized electronics that make it possible to analyze signals with just a computer and a small kit.
