2. Objective: To compare theoretical predictions of calculated quantities to EWB simulation results as well as with NI circuit board measurements. Illustrate that actual circuit board measurements (NI) differ from nominal values (calculated values). Working with graphs in signal express helps familiarize you with graphs on circuits 3. Procedure: Using the DMM; we measured the actual value of the 5V power source. We then measured the actual value of the 47 ohm resistor and the 120mH inductor using the DMM and Fluke RCL meter. After this signal express was set up to produce the required signals. Using only components with exact measured values, the circuit was built. We then ran the simulation through the circuit just built and saved all plots. 4. Results: A.) NOMIN AL MEASUR ED % ER RO R RL 47 56.7 20. 60 % R L N/A 146.3 0% L 120mH 116.4mH -3% B.) Predicted Ʈ = L/R = 573 μs
