Assignments
• Assignments:
– Pre-Lab assignments, which are necessary in order to understand and finish
lab work. Submit a copy of pre-lab to Instructor during the first 5 minutes of
lecture for full credit. There will be 12 pre-labs.
– There will be 14 lab sessions in NH 129B with the TA and instructor. While the
lab session is carried out in a group of two, the Lab report is your own individual
assignment. Lab reports must follow a specific format announced in class and
are due a week after the lab is conducted.
– Reading Assignments: The assigned reading material will help you better
understand the concepts. Materials from the reading assignments may also be
part of course exams.
– Examinations: One in-class exam (midterm), one lab proficiency exam
(midterm), and one final lab proficiency exam.
– In rare circumstances (medical emergencies, for instance) exams may be
retaken and assignments can be resubmitted without penalty. Labs might be
redone with the help of the TA during office hours.
– Missed deadlines for assignments: Maximum grade drops 25% per late day
(every 24 hours late).
Dan O. Popa, Intro to EE, Practicum, Spring 2015
Honor Code
•
Academic Dishonesty will not be tolerated. All homeworks and exams are
individual assignments. Discussing homework assignments with your
classmates is encouraged, but the turned-in work must be yours. Discussing
exams with classmates is not allowed. Your homeworks will be carefully
scrutinized to ensure a fair grade for everyone.
•
Random quizzes on turned-in work: Every student will be required to answer
quizzes in person at least once during the semester for homework and lab
reports. You will receive invitations to stop by during office hours. Credit for
turned in work may be rescinded for lack of familiarity with your submissions.
•
Attendance and Drop Policy: Attendance is mandatory in order to get full credit
for class participation and class attendance. If you skip classes, you will find the
homework and exams much more difficult. Assignments, lecture notes, and
other materials re going to be posted here, however, due to the pace of the
lectures, copying someone else's notes may be an unreliable way of making up
an absence. You are responsible for all material covered in class regardless of
absences.

What is LabVIEW
• LabVIEW is a programming environment
designed by Electrical Engineers from National
Instruments (NI), and running on Hardware such
as NI myDAQ
• LabVIEW Introductory Video
• LabVIEW relies on graphical symbols rather
than textual language to describe programming
actions
• The principle of dataflow, in which functions
execute only after receiving the necessary data,
governs execution in a straightforward manner
Dan O. Popa, Intro to EE, Practicum, Spring 2015
How does LabVIEW work?
• LabVIEW programs are called:
– Virtual Instruments (VIs)
– because their appearance and operation
imitate actual instruments.
• However, they are analogous to main
programs, functions and subroutines from
popular language like C, Fortran, Pascal,
…
Dan O. Popa, Intro to EE, Practicum, Spring 2015

LabVIEW Programs Are Called Virtual
Instruments (VIs)
• Front Panel
• Controls = Inputs
• Indicators = Outputs
• Block Diagram
• Accompanying “program”
for front panel
• Components “wired”
together
Dan O. Popa, Intro to EE, Practicum, Spring 2015

Dan O. Popa, Intro to EE, Practicum, Spring 2015
Dataflow Programming
• In this case, the block diagram executes from left to right, not
because the objects are placed in that order, but because the
Subtract function cannot execute until the Add function finishes
executing and passes the data to the Subtract function. Remember
that a node executes only when data are available at all of its input
terminals and supplies data to the output terminals only when the
node finishes execution.

Intellectual Themes of EE
• Modularity (ex: device)
– Manage complexity by reusing simple components
(electrical, mechanical or code) nomenclature: devices
• Abstraction (ex: circuit, system)
– Represent complex systems by connecting modules
using interconnects
• Block diagrams, Data flow diagrams (state machines), signal
flow graphs, electric circuits
• Modeling (ex: electronic vs electric)
– Represent behavior of systems using mathematical
abstractions
Dan O. Popa, Intro to EE, Practicum, Spring 2015
System Modeling
• Building mathematical models based on
observed data, or other insight for the system.
– Parametric models (analytical): ODE, PDE
– Non-parametric models: ex: graphical models - plots,
or look-up tables.
– Mental models – Ex. Driving a car and using the
cause-effect knowledge
– Simulation models – ex: Many interconnect
subroutines, objects in video game
Dan O. Popa, Intro to EE, Practicum, Spring 2015
Circuit Elements as Modules
• Defined by Electro-Magnetic Laws of
Physics: Ohm’s Law, Kirchoff’s Laws,
Maxwell’s Equations
