Lab Report - Lab 11: Complex Numbers TIMS
Introduction
The objective of the lab is to utilize the TIMS unit to see how imaginary and real parts of functions look like graphically.
Procedures
Pre-Lab Exercise:
A.1.5) Sum = ARB1+ARB2 = 1 + j1
A.1.8) Change the ARB2 phase to -90◦, press “Load ARB”, and record the
complex number for the summed value. Record the complex number in both
rectangular and polar form.
A.2.3) Explain why the XY plot displays a circle.
The plot displays a circle because it is showing a sin wave and
that sin wave is going ina circle when it comes to looking at the xy
values
A.2.4) How does this correspond to what you see on the PicoScope?
When removing ARB1 form the scope the XY graph shows only the y
direction change of the circle so it appears as a straight line
through the y axis.
A.2.5) How does this correspond to what you see on the PicoScope?
When removing ARB2 from the scope it is the same as before but
instead of the vertical component remaining only the horizontal
component remains with no height.
A.2.6) Write the equation for signals at ARB1 and ARB2 as a function
of time in the form: Acos(t + )
ARB1: 1cos(t-15)
ARB2:
1.2cos(t+75)
B.2) Create the functions described in B.1 and B.2. Include both
Matlab “.m” files in your submission.
Shown in code section below.
C.4) Comparing the output sum signals from steps 3 and 4, are
the results as expected? Explain. The sums are similar but not exactly
the same as the TIMS machine won't make perfect waves and the matlab
is run off of ideal conditions. Additonally, the MATLAB code does some
rounding itself.
D.8) Record the ChB amplitude in Table 1. The first one is done
for you.
Conclusion
What did you enjoy about this lab?
I enojoyed using the TIMS machine for the last time
What didn’t go well in this lab?
Understanding what was really going on did not go well during lab but
it made sense afterwards.
How would you improve the lab experiment for future classes?
I would improve this lab by replacing it with making matlab code
instead. In person part felt pointless.
