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?
