How to PROVE Linearity | Signals & Systems (Superposition Explained for the 100th Time)

Going through how to prove whether a system is linear or nonlinear using the superposition principle. I'll walk through the steps for checking BOTH additivity and homogeneity with ONE GOATED SUPERPOSITION PROPERTY, how to set up the proof properly, and what to look for when a system isn't linear. Basically how to approach these questions every single time instead of just guessing based on what the equation looks like. #SignalsAndSystems #Linearity #ECE265
