3340/4430/5430 Spring Semester, 2001
All
of the electronics experiments are designed to be completed in one week. The
first two experiments are introductory. Experiments 3 through 6 cover
operational amplifiers and would usually be done in sequence. Experiments 10
and 11 cover digital electronics, and should be done in sequence. Experiment 13 and 14 are “advanced”
electronics experiments. They may be
done by students who have already taken 3330.
They currently have no associated manual.
1)
Absolute Measurement of the Faraday. Measurement of the Faraday in terms of
SI units of mass, length, and time. (The Faraday is the charge in Coulombs of
Avogadro's number of electrons.)
2)
Electronic Instruments. Introduction to oscilloscope,
function generator, counter/timer, and digital multimeter.
3)
DC measurements, dividers, and bridges. Voltage dividers,
Wheatstone bridges, and 4-point measurements.
4)
Filters and Waveform Shaping. Use of passive components
(R, C, and L) to construct simple filters. Measurement of frequency response.
5)
Operational Amplifiers and Negative Feedback.
Introduction to operational amplifiers. Noninverting amplifier connection.
Thermocouple amplifier.
6)
Virtual Ground Amplifiers. Inverting (virtualground)
amplifiers. Integrator used as a magnetometer.
7)
Positive Feedback and Oscillators. Stability of feedback
circuits and active LC oscillator.
8)
Transistor Amplifiers. Twostage amplifier made from NPN
bipolar transistors.
9)
Photometer and Lock-in amplifiers. Introduction to
photodiodes, light emitting diodes, and lockins.
10)
Digital Logic Elements. Introduction to digital
electronics.
11)
Counters and Decoders. Digital circuits for binary
counting and for binary decimal conversion.
