The power spectral density of the acoustic signature of
Dungeness crab was calculated by the use of digital computer.
The signal produced by the Dungeness crab was an analog signal.
Therefore a conversion of the signal from analog to digital was
necessary. This was done by sampling the acoustic signature...
A new, computer oriented system for automatic, in situ
monitoring of water quality is proposed which makes full and effective
use of modern computer technology. The main objective of this thesis
work was the development of the concept for in situ computer controlled
experimenting as a reasonable and effective means...
A non-volatile electrically alterable read-only memory using
an MOS field effect transistor with a threshold voltage which depended
upon the position of ionic charges for its memory was fabricated.
The conventional silicon dioxide layer was replaced by a composite
layer consisting of thermal silicon dioxide, electron beam
evaporated aluminum oxide,...
The feasibility of using the Franz-Keldysh effect in practical
light intensity controlling devices was investigated.
Reverse-biased diodes made from CdS were implemented to obtain
high electric fields necessary for the effect. The three types of
diodes studies were: MIS, metal-semiconductor barrier, and p⁺-n
heterojunction. An expression for the change in...
The purpose of this study is to investigate radiation
losses in microstrip circuits. Expressions are derived to
evaluate the radiation resistances (or conductances) for
single terminated, open and short-circuited lines. The
quality factor Q of open and short-circuited stubs is
evaluated. An analytical procedure is formulated to
evaluate the radiation...
CP1100/GPIB Interface is an interface between the "General
Purpose Interface Bus", which is an implementation of the Universal
Bus described in IEEE Standard 488-1975, and Unibus. This interface
enables TEKTRONIX CP1100 series controllers to operate
GPIB- compatible instruments connected to the General Purpose
Interface Bus. The designer can now incorporate...
REGTRAN (REGister TRANsfer), a hardware description
language and SYSSIM (SYStems SIMulation), a simulator for the
system described by REGTRAN were originally developed by Edward
Pett, Jr [33] at the University of Texas at Austin. These two programs
are successfully used to simulate many digital systems of
complex nature. It is...
An important step in the design of digital networks lies in the derivation of the switching formulas which describe the combinational logic networks in the system. In most large systems the number of gates and the number of connections are major factors that affect the cost of the system. An...
This report is concerned with the analysis of the effect of
finite wordlength, channel capacity and source rate in digital feedback
control of linear systems. The cases considered are (1) finite
wordlength A/D conversion, no feedback delay, ideal ROM (read
only memory) controller; (2) finite A/D wordlength (source rate),
state...
