10. Pulse Code Modulation - Digital Audio Fundamentals

Pulse Code Modulation is an encoding mechanism, a way of representing digital data for the purposes of transmission and storage. But what form does this encoding take, and why is it needed? In this video, we'll explore the the concept of encoding and modulation as a corner stone of digital audio. We'll start from first principles and discover different modulation strategies and their advantages, and naturally arrive at why PCM is so resilient and has survived the test of time.
