   Which Shannon and Nyquist would tell us is in a properly   
   implemented system, is indistiguishable from instantaneous.   
   It makes no difference if during that interval the signal   
   was continuously at some level or was a unit impulse at   
   that level or a bunch of noise that averaged out at that   
   same level.
