Labs will be posted here on Monday morning and are
due in Glennan 308 during your lab periods, one week after they are
assigned.
What to do if you think the equipment is
not working.
Manuals for the power supplies, oscilloscopes,
meters, waveform generators, and Benchlink software.
(January 20-21). Please meet with Lab TAs in Glennan
308 at the regularly scheduled laboratory times. Students will sign up for
lab groups (of 2 students each) and be given a brief introduction to lab facilities.
Because of the
observance of Martin Luther King Day special arrangements will
be announced for the Monday January 19th lab sections to receive the laboratory
introduction and sign up for laboratory teams at another time.

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..

(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 23-25).
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.

THEVENIN EQUIVALENT CIRCUITS
(This lab will
be done in Glennan 308 during February 23-25. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 1-3).

(This lab will
be done in Glennan 308 during March 1-7. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 15-17 — 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.
- Lab 8 (PDF, 84 kB)
NON-LINEAR OP-AMP CIRCUITS
(This lab will
be done in Glennan 308 during March 15-18. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 22-24 ).
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 the Schmitt trigger for the same noisy
signal.

MEASURING RC TIME CONSTANTS
(This lab will
be done in Glennan 308 during March 22-24. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section March 29-31).

using a digital oscilloscope.

EXPONENTIAL WAVEFORM IC
(This lab will
be done in Glennan 308 during March 29-31. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section April 5-7).
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
lectrure notes descibe 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.

PASSIVE RL AND RC FILTERS
(This lab will
be done in Glennan 308 during April 5-7. The corresponding lab write-up
(ONLY ONE PER GROUP) will be due during your lab section April 12-14).
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 derive the frequency response of 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.
