Three engineering students

Three engineering students were gathered together discussing the possible designers of the human body. One said, "It was a mechanical engineer. Just look at all the joints." Another said, "No, it was an electrical engineer. The nervous systems many thousands of electrical connections." The last said, "Actually it was a civil engineer. Who else would run a toxic waste pipeline through a recreational area?"

Signal Processing Engineers

Q: How many signal processing engineers does it take to change a light bulb?
A: Three. One to Fouriev transform the light bulb, one to apply a complex exponential rotational shifting operator, and one to inverse transform the removed light bulb.
