Calculating power in a waveform ( V and I ) -- from the simple AC 60Hz case, to a more complex PWM signal, or the losses in a switch... To append to an example like this, I would explain to students that calculating power is very important because it tells how much a certain component heats up, and if the power consumed by the component is greater than the power rating, then you run the risk of this component failing (visibly smoking or maybe even catching on fire in the right circumstance). Complex numbers are used a lot with AC signals (as far as I can tell, half a year into an EE study). So your maximum register value of 4095 would represent 10150. My education taught me all of the necessary skills I needed to succeed as an Electrical Engineer. I am putting these here to remind me to post, I am an older student but dropped out in 7th grade but having a background in fixing things helps me connect the math theory to the real world. Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively), is the practice and study of techniques for secure communication in the presence of third parties called adversaries.
