Lecture 23 - Signal Integrity and Input Impedance

Date: 11/8/16

Summary

Any time we amplify, process, or digitize an electrical signal there will be noise. One of the greatest challenge in research equipment is making sure that the signals remain as pristine and low noise as possible. In this class we will discuss how to keep your signals clean as well as how input impedance works.

Class Plan

• What is signal integrity?
• Crosstalk
• RFI
• Ringing
• Filtering
• Shielding
• Layout considerations
• Input impedance
• Impedance matching

Activity

• Show the effects of impedance mis-match with an oscilloscope, function generator, and termination resistor. Ask students to explain what we are seeing on the display.
