Goals

Upon completion of this module,

• Students will be able to select an appropriate analog to digital converter for a particular measurement situation
• Students will be able to critique selections already made by someone else for a converter in an instrument, including explanation or computation of:
  • Useful resolution
  • Noise or signal-to-noise ratio
  • Distortion and aliasing
• Consequently, students will be able to explain how much chemical information is being accurately reported by a digital instrument, how much additional information is available but is missed because of instrument design, or what measurement errors and misunderstandings are a consequence of a digitization scheme.
