Heaviside Function: From Nothing to Everything in One Instant

The Heaviside function is a simple step function that “switches on” at a chosen point. In this short video, we build intuition for how it works and why it’s so useful for modeling sudden changes in real-world systems. It also naturally ties to the delta function covered earlier, so take a look back at that video if you need a refresher: https://youtu.be/VwQDs5l274o This concept also comes up in impulse response which is covered in a later video of this series: https://youtu.be/3vqf2aEcOo4
