AC signals #1, May 18, 2011, Part A

The purpose of this experiment is to build a ac circuit and analyze what happen to it with phasor. This lab was done by as whole class. The circuit and analyzing graph is provided by professor. First we look at the graph of 2 different source. Then we calculated Vrms and we find the Z(impedence) for capacitor. Then we find the phase angle between the capacitor and voltage source.

Vrms	2.12V
Vrms(dmm)	2.00V
Zcap	-716.9j
tx	90micros
phase angle	71.93

Oscilloscope 101 May 9th, 2011

The purpose of this lab is to familiarize the use of Oscilloscope 101. First we had a frequency generator to plug into the scope. Then we regenerate some frequency and turn on the scope. We selected the range of voltage and time. Then we switch the coupling button to ground. We set our ground at the center of the screen. Then we turn the coupling to dc and ac for analyzing the graph. First part we analyzed the graph of normal wave. The picture shows clearly how the graph looks like. then we made it to show square wave and analyze it.
