AC Signals #1

The above circuit was analyzed with professor's computer.
Anticipated Vrms = 2.12 V
Actual Vrms = 1.97 V
Zcap = -717j Ohms
Vcap = ~2V
Vcap,rms = 1.6 V
t_x = 90 microseconds

Oscilloscopic Skeleton

The point of this lab was to become acquainted with oscilloscopes and how to use them for determining the frequency and amplitude (voltage) of an oscillating current.
Part 1 - Displaying and Measuring a Sinusoid
The FG was set to have f = 5kHz and peak to peak amplitude to have 5V. We measured the period with the O-scope to be 200 microseconds. The the peak to peak amplitude measurement was off by a factor of 4.: 20 V. Same with the zero to peak amplitude: 10 V.we got the Vrms to be 7.07V.

Using the DMM on the leads: VDC = 0.06 V, VAC = 4.07 V

Part 2 - Including a DC offset
The difference between the DC and the AC coupled is a change along the y axis. (voltage)
Using the DMM again: VDC = 2.5 V, VAC = 3.28 V

Part 3 - Square Wave
Again with DMM:
VDC = 2.5 V
VAC = 5.17 V

Vrms = 3.66V
Part 4- Measuring two Mystery Sources

Channel 1:
DC V= 0 V
f = 100 Hz
Pk -to- pk Amp: 0.6 V

Channel 2:
DC V=0.5 V
f = 6.25 kHz which is about 6.06 kHz (the actual frequency)
pk -to-pk Amp: 0.3 V

Thus we learned how to use oscilloscopes to learn things about alternating/time dependent currents.
