Lab Handouts for the UIUC Physics 406 POM Course:
The following lab handout briefly describes the experimental/lab setups and lab equipment that
we currently have available for use in this course.
The following lab handout briefly describes *possible* experiments
that *could* be carried out in the lab portion of this course - things that potentially would be
interesting and/or fun to investigate! This is certainly/by no means meant to an exhaustive/all inclusive list!
The following lab handout describes how to run and use the MATLAB Wav_Analysis program
(written by 2004 NSF REU Summer Student, Joe Yasi {Rensselaer Polytechnical Institute}) to carry out harmonic/spectrum
analysis of sounds produced (arbitrary) musical instruments and recorded with a digital sound recorder.
The following lab handout describes how we absolutely calibrate pressure and particle-velocity microphones.
The following lab handout discusses the distinctions (and the relations) between measurements of time-domain vs. frequency-domain sound field quantities.
The following lab handout describes how to setup, run and use the Hewlett-Packard HP-3562A
Dynamic Signal Analyzer to carry out the simplest kind of spectral analysis measurements - power spectral densities, Gxx(f) = |x(f)|^2.
The following lab handout describes how to setup, run and use the Hewlett-Packard HP-3562A
Dynamic Signal Analyzer to carry out general spectral analysis measurements.
The following lab handout describes how to setup, run and use the Hewlett-Packard HP-35670A
Dynamic Signal Analyzer to carry out the simplest kind of spectral analysis measurements - power spectral densities, Gxx(f) = |x(f)|^2.
The following lab handout is for the closed-open organ pipe lab/demo experiment.
The following lab handout contains information on how to run the Guitar.exe
computer demo/simulation of vibrating strings on a guitar, and harmonic content thereof.
{This handout is the final report of Tobias Schmitter's UIUC Physics 398EMI Project, Fall Semester, 2000.}
The following lab handout describes how measurements of the complex mechanical vibrations
of e.g. stringed can be carried out using the Sonic DAQ program.
The following lab handout briefly describes/summarizes the measurements
that can be carried out to investigate the electromagnetic properties of electric guitar pickups.
The following lab handout briefly describes the setup and technique used for winding electric guitar pickup coils.
The following lab handout that describes a PC-based data acquisition system
we developed at UIUC to enable us to measure/study the properties of 12A*7/ECC8* type dual triode
tubes, map out the triode characteristic curves and extract the triode tube parameters, gm, mu, Rp
as a function of grid-cathode potential (V_gk), plate-cathode potential (V_pk), cathode/plate current (I_k/I_p).
The following lab handout that describes a PC-based data acquisition system
we developed at UIUC to enable us to measure/study the properties of "standard" 12A*7/ECC8* type triode
voltage amplifier as a function of input signal and input frequency,
grid-cathode potential (V_gk), plate-cathode potential (V_pk), cathode/plate current (I_k/I_p), etc.
The following is a lab handout that describes a PC-based data acquisition system
we developed at UIUC to enable us to measure/study the DC current-voltage (I-V)
relation of 2-lead electronic devices - such as resistors, diodes (of all kinds), varistors, etc.
The following lab handout explains how to calculate the inharmonicities associated with real musical instruments.
The following lab handout explains how to calculate the center, high/low frequencies for octave, 1/2 and 1/3 octave bands.
