myDAQ homework problem: AC Circuits > RMS Value > Arbitrary Waveform

[edoering]

Problem Statement: Determine the average value and effective DC value (also called RMS value) of the periodic waveform.

Analysis:

• Show your complete solution process
• See similar worked problems at Circuits Learned by Example Online (CLEO)

myDAQ Measurement:

• Create v(t) with NI ELVISmx Arbitrary Waveform Generator; use 50 kS/s update rate
• Extract average value with RC lowpass filter (R = 10 kW, C = 100 mF)
• Observe v(t) and filtered version with NI ELVISmx Oscilloscope
• Report average value and effective value as read from oscilloscope numerical display
• Follow along with the video clip below to confirm correct operation of your measurement setup:

Comparison:

• Report percentage difference between calculated values and measured values
• Include screenshot of oscilloscope display
