Foil 15 What is so important about Digital ?

From Untitled presentation Jamesvill DeWitt Middle School 5th Grade -- 2 April 97. by Geoffrey C. Fox


1 Analog as in current Cable Satellite or broadcast TV or radio represents informations by WAVY SHAPES
  • Shapes can be arbitrary and if changed (distorted) canNOT be easily corrected
2 Digital as in current computers represents everything by NUMBERS and uses "error-correction" so that you receive EXACTLY what is sent with NO distortion of text or images
3 So information is more precise
  • Can do online banking
4 and looks better -- your great art piece is not distorted or the medical picture is transmitted without adding or subtracting tumors/pathologies etc.
