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
- 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.
