School Textbooks show nice sinusoidal and square wave shapes to work with. In the real world clean data like that almost never happens. If it does, it is almost always because somebody else took care of smoothing out the data before you got hold of it. e.g. of more typical sensor reading data of which you need to pick the "correct" value: (1, 3, 5, 65, 68, 70, 75, 80, 82, 85, 540, 555). I sorted the data to make it more obvious. | |
