Hi all!
Maybe it's a stupid question but I was reading this http://www.dspdimension.com/PDF/DftAPied.pdf and it confused me a bit. Theoretically, if we have a sample rate at 1000Hz, the highest possible pitch will be 500Hz. But is there an opposite limit? Is there a "lowest possible pitch" for different sample rates? Is DC always there no matter what SR is or the lowest frequency boundary is moving also?
