So in  in an ideal word i world  if the noise were always the same , then , when you subtracted it the worst that i you would get would be a zero. I mean , the lowest you would get would be a zero , cuz i if there was no other energy there you 're just subtracting exactly the noise.
Right.
Mm - hmm ,
Yep , there 's all  there 's all sorts of , uh , deviations from the ideal here.
