Volunteering to build a circuit.

"The professor I remember most is Dr. Aram Budak. I first met him when I was sent to get his approval to change my major to Electrical Engineering. He asked me why I was interested in changing majors, accepted my answer, and approved the transfer. He was far more intimidating as an instructor. He knew his stuff and didn't tolerate sloppiness or laziness. His amazing magic marker board was capable of solving most tough homework problems.

"I vividly remember impulsively volunteering to build a circuit that Dr. Budak proposed in lecture but had not built. It was an oscillator based on a bandstop filter. His theory worked, it oscillated at the bandstop frequency but also every harmonic. I wasted an enormous amount of lab time trying to use it for a lab project. Only through his kindness was I able to repair the lab project and achieve a passing score."
