Hi, I'm trying to understand the basics of boolean logic gates and I'm stuck with latches. I think I don't really understand the concept of feedback or maybe it's something else but I haven't been able to understand how a basic RS NAND latch works. Could somebody please explain it in simple words or give a link to an explanation? Thank you very much in advance. PS: "http://www.play-hookey.com/digital/rs_nand_latch.html" [Broken] is what I'm reading.
