Introduction to Process Control Lab
Use the multifunction generator for the input and use both channels of the Tektronix virtual scope to display the input and output voltages.
Create a table of your input and output voltage at dc, 250 Hz, 500Hz, 750Hz, 1kHz, 5kHz, 10kHz, 50kHz, 100kHz. Measure additional frequency points in order to get a nice set of data for the drop off. Be sure to capture several screenshots of the Tektronix virtual scope.
Given the output voltage at dc, what is the voltage 3dB down? In other words, what is the output voltage at the 3dB point? You should calculate this.
Using your simulation, change the frequency of the input voltage until the output voltage is that associated with your 3dB point. What is the frequency of the signal? That is your critical frequency. Take a screenshot of the scope. Add these measurements to your table. Also, put in your report this frequency. What is this frequency called?
Create a plot of your data (you can do this easily in Excel) and copy and paste the plot into your report.
