CHAPTER 4: SIGNAL TO NOISE RATIO

usually done by a computer as data is being collected (real time) -limitations include loss of detail, application to only complex signals that change rapidly as a function of time -for square wave or repetitive pulsed outputs where only ave. amplitude is important, it is very important -moving window averaging means point I is the ave. of 1, 2 and 3, point 2 is an ave. of points 2, 3 and 4 ... ................
