Wow, Dr. Oliphant taught my undergrad signal processing class. It was by far the most difficult class I've taken in my life and I have a PhD.,(reply>), Thank you for sharing this. You made me laugh out loud-- great delivery!,(reply>), @Hu Mann I've had plenty of difficult classes over the years, but his class was crazy. It was also his first year teaching, so none of us had any idea what we were signing up for. He was a good teacher though.,(reply>), He talks about his teaching approach a little on the podcast, he says he was of the School of thought you don't drop down to a students level, you show them the level they need to get to. He has changed a bit over the years but that was his formative attitude when teaching. Sounds like a tough but passionate teacher who wanted his students to rise to the challenges in his class. You are lucky to be in his class though!
