This thesis is concerned with the design of the high speed tape
read-out and tape feed control circuits and interface to the PDP-8/L
Computer system, The system was designed to operate under the
programmed data transfer mode of the computer, and is compatible
with the computer manufacturer's system.

This thesis is concerned with the design of the interface--Read,
Write and control circuits--of the magnetic disc with the PDP-8/L
Computer system. The interface was designed to operate under the
Data Break transfer mode of the computer and is compatible with the
computer manufacturer's system.
The Data Break option was...
This paper describes an inverter design which provides voltage
regulation against variations in both the input voltage and load impedance.
This design modifies the so-called parallel inverter, which
consists of two silicon controlled rectifiers (SCRs) operating in a
push-pull arrangement, to include a third regulating SCR. This
regulating SCR is...
The purpose of the thesis is to design, construct,
program, and test an automatic integrated circuit test
system. The class of integrated circuits tested was restricted
to digital integrated circuits. The general concept
of testing a digital integrated circuit is based on
the truth table of that circuit. A combination...
Recent acheivements in high speed digital integrated
circuits has prompted the system designers to search for
a practical method of inter-connecting these high speed
circuits. This paper describes the implementation of the
microstrip transmission line on a high speed digital
data bus. Transmission line and characteristic impedance,
termination with single...
This thesis is concerned with the design of a speech recognition
system to recognize digits 1, 2, 3 and 4. The system was designed
by using the characteristics of the spectral patterns of amplitude vs.
time at discrete frequencies. Data obtained for digits 0 to 9 are presented.
The outputs...
In this paper the characteristics of multi-conductor transmission
lines have been investigated for a variety of termination conditions
by using the differential equations and matrix methods.
Equations showing the characteristics of traveling waves along loss-less
multi-conductor systems are derived.
Line parameters were evaluated by experiments and by calculations.
The results...
A fluorescence anisotropy spectrophotometer known by
the acronym GUS has been in use at Oregon State University
in the department of biochemistry and biophysics for
several years under the supervision of Dr. Irvin Isenberg.
Dr. Isenberg wished to improve the accuracy, versatility,
speed of data acquisition, and ease of operation...
The junction-field effect transistor has been improved technically,
so it is appropriate in analog switching applications. In this
paper, use of a junction FET as an analog switch is described.
Feedthrough of current from the gate control voltage causes a
noise at the output during the switching transient. Peak noise...
