What happens mathematically when you flip a switch ON? 🔛

In this video on Engineering Logic, we introduce the *Unit Step Signal* $u(t)$, the fundamental building block of Signals & Systems:
1. *Continuous Time $u(t)$:* Definition
2. *Discrete Time $u[n]$:* How the sequence behaves at $n=0, 1, 2...$
3. *Physical Meaning:* Why it represents a sudden application of DC voltage (like connecting a battery to a circuit).



We also discuss the value of $u(0)$ and why it is technically undefined (or considered $1/2$ in some textbooks).
