Complex Exponential Signals and Phasors, Explained! | V2

Every sinusoidal signal can be written as a spinning arrow in the complex plane. I've been teaching signal processing for years, and this is the trick that finally makes AC circuits and frequency analysis click. That spinning arrow is called a phaser. It captures amplitude and phase, but strips away the messy time dependence using Euler's formula. So instead of juggling trig identities, you just add complex numbers like vectors. The complex exponential e to the minus i omega t is the foundation underneath it all. And once you see signals this way, frequency domain analysis stops feeling like magic.
