Simply double click on these downloaded files to extract the simulation, and
then run the simulation to perform Lab 1. You will prepare individual reports
for this first lab.
REPORT TO LABORATORY (January 18-January 19) during scheduled
lab times in Glennan 308. Students will sign up for lab groups (of two students)
and
be given a brief introduction to lab facilities by the Lab TAs during this lab
meeting. SPECIAL ARRANGEMENTS WILL BE MADE FOR THOSE STUDENTS WHO WERE SCHEDULED
FOR
LAB ON JANUARY 17TH.
Lab 2 LabVIEW BASICS (This lab will
be done in Glennan 308 during January 24-26. The corresponding lab write-up
- ONLY ONE PER GROUP - is due during your lab section January 31-February
2).
This lab covers basic LabVIEW programming concepts.
Although we will not use LabVIEW extensively in ENGR 210 it is commonly used
by biomedical, chemical, mechanical and most other engineers in industry. NOTE:
Monday laboratory groups will have a short orientation( at the beginning of this
week's lab section) to the lab and assignment of partners to
make up for the lab missed last Monday.
Lab 3 LabVIEW Programming (This lab will
be done in Glennan 308 during January 31-February 2. The corresponding
lab write-up (ONLY ONE PER GROUP) will be due during your lab section February
7-9).
This lab covers using LabVIEW
to make very simple voltage measurements using a suitably equipped computer and
comparing these measurements with the same measurements made using a Digital
MultiMeter.
Lab 4 LINEAR CIRCUITS: KCL, KVL AND SUPERPOSITION (This lab will
be done in Glennan 308 during February 16-18. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section February 7-10).
You will construct a linear circuit of nine elements; measure the DC
currents and voltages in the circuit; and validate
Kirchoff's Laws and the superposition property for this linear circuit.
Lab 5 THEVENIN EQUIVALENT CIRCUITS (This lab will
be done in Glennan 308 during February 14-16. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section February 21-23).
You will construct a linear circuit of eight elements (two voltage sources and
six resistors); measure the i-v characteristics of this circuit at several
output points, and determine the Thevenin equivalent circuit for each output.
Lab 6 FUNCTION GENERATOR AND OSCILLOSCOPE (This lab will
be done in Glennan 308 during February 21-23. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section February 28-March
2).
This lab introduces you to two of the most important instruments you can use
to generate electrical test signals (the function generator) and the device which
you can use to measure the time dependent behavior of circuits (the oscilloscope).
Lab 7 THE OP AMP (This lab will
be done in Glennan 308 during February 28-March 2. The corresponding lab
write-up (ONLY ONE PER GROUP) will be due during your lab section March 14-16
- AFTER
SPRING BREAK).
This lab will introduce you to the integrated circuit OP AMP. In this lab you
will learn how to power the integrated circuit OP AMP, construct simple inverting
and non-inverting amplifier circuits based upon the OP AMP, and measure
their operating characteristics.
Oscilloscope Probe Manual .
This document describes the electrical behavior of the oscilloscope probes used
in the circuits lab.
Lab 8 NON-LINEAR OP AMP CIRCUITS (This lab
will be done in Glennan 308 during March 14-16. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 21-23).
This lab will introduce you to non-linear OP AMP circuits of which the comparator
discussed in class and homework is one. In this lab you will build a comparator
circuit using an OP AMP, measure its performance for signals with and without
noise, and examine the performance of another circuit, the Schmitt trigger,
for cleaning up noisy signals.
Lab 9 MEASURING RC TIME CONSTANTS (This lab
will be done in Glennan 308 during March 21-23. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 28-30).
This lab will introduce you to the experimental measurement of RC time constants
for exponential waveforms using a digital oscilloscope.
Lab 10 THE 555 INTEGRATED CIRCUIT TIMER (This lab
will be done in Glennan 308 during March 28-30. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section April 4-6).
This lab introduces you to one of the most popular integrated circuits -- the
555 timer. You will use it as a one-shot (a popular circuit for
removing noise from electrical signals),
an oscillator, and a water level sensor.
555 Lecture Notes (These
are lectrure notes describing the internal structure of the 555 (essentially
two comparaors and a switch) and show how to perform 555 timing calculations
based upon your knowledge of exponential waveforms.
Lab 11 PASSIVE FILTERS (This lab
will be done in Glennan 308 during April 4-6. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section April 11-13).
This lab will examine the frequency dependence of capacitors and inductors in
simple circuits. You will construct simple filter circuits and measure the
magnitude and
phase response of these circuits to sinusoids of various frequencies.
BandPass Filter Analysis .
These notes show the derivation of the frequency response for the bandpass filter
used in Lab #11 (Figure 6). The analysis is complicated because the two filter
sections (a lowpass and a highpass) cannot be electrically separated from each
other.
This lab is the last lab of the semester!
Lab 12 ACTIVE FILTERS (This lab
will be done in Glennan 308 during April 11-13. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during class Wednesday April 20th.).
This lab will measure the magnitude and phase response of active filter circuits
as a function of frequency.
Second
Order LowPass Filter Analysis .
These notes show the derivation of the frequency response for thefirst and second
order lowpass filters used in Lab #12 (Figures 4 and 5).
