Lab 2. Filters

 

Objectives

  • To evaluate active and passive filter circuits using analysis, simulation and circuit measurement

Materials

  • Diligent Analog Discovery II NI Edition
  • Waveforms 2015 software (Network Analyzer)
  • Analog discovery parts kit
  • NI Multisim workbench

Theory

To be completed by you

 

Passive Filters

Active Filters

Include circuits of your chosen filters

 

Procedure

  1. Select a filter design from your textbook. Design, simulate fabricate and test and perform the analysis for your filter.
  • Complete #1 for one passive filter
  • Complete #1 for one Active filter
  • Measure component values an use the measured values for your analysis.
