Question

Settings for the 5.2A function generator: • AC Sine Wave • f = 30 Hz • Phase Shift = 50° • Offset = 0 V • Amplitude = 2 V

B. Simulate the circuit seen in Figure 5.2. Use the same function generator settings as 5.2A. Record three to four cycles of both the input and output. Using the cursors on the oscilloscope, measuring the time shift between the maxima of the two waves, Δ, and use it to calculate the phase shift Δφ using the following equation C. Using the cursors in the oscilloscope, measure the period T for both the input and output waveforms of Figure 5.2. Use this period to calculate the frequency, f. Are the frequencies the same for the input and output waveforms? 12 : : 250Д : Figure 5.2: Lab #5 Basic AC RC Circuit
