This post has two assignments:

 

1. EXPERIMENT #3


SUPERPOSITION
OBJECTIVES
1. To become familiar with features provided by a computer-based circuit
analysis program.
2. Use the principle of superposition to investigate a resistor network.
EQUIPMENT
IBM PC/XT/AT or equivalent
LTspice Program
BACKGROUND
Read section 4.3 on Superposition in the text,
Fundamentals of Electric Circuits by
Alexander and Sadiku. If using
All About Circuits (online text) see the section
“Superposition Theorem” in Chapter 10.
CIRCUIT DIAGRAM
Figure 3.1

PROCEDURE
1. Theoretically show that the input-output relationship of the R-2R ladder circuit of
Figure 3.1 is V
o = V1 / 8 + V2 / 4 + V3 / 2 using superposition.
2. Run LTspice analysis on the circuit shown in Figure 3.1. Fill in the data in Table
3.1.
DATA

V3, volts V2, volts V1, volts Vo, volts
0 0 0
0 0 5
0 5 0
0 5 5
5 0 0
5 0 5
5 5 0
5 5 5

Table 3.1
CONCLUSION
Given the information provided in your theoretical work and what you found, discuss the
operation of this circuit.
Show that the data in Table 3.1 is consistent with your theoretical data.
Research using the WWWeb the operation of a digital-to-analog converter. How does
this device relate to this lab?

 

2.  SELF-CHANGE PROJECT

The purpose of this assignment is to solidify skills associated with developing a behavior management plan. Concepts discussed in class will be used in the development of a plan that centers on a particular behavior in which you wish to engage. You will be researching your health behavior topic, the health impacts of that behavior, as well as steps to take to change that behavior and also adhere to (stick-to) the health behavior change. It is recommended that you select a behavior for which you are in a preparation stage of readiness to change (i.e., ready to change soon, have tried in the past and was unable to sustain change, need a “boost” to get going in the change processes, etc.). You are to create a behavior management plan, complete with a behavior management contract, and implement the plan over 3 weeks (it has been suggested, although not necessarily proven, that it takes 28 days to create a habit, so this will put you on your way). The purpose of this assignment is to apply sound behavior change planning skills as you start on a 21-day journey.
