This thesis is a development of two sets of equations predicting the switching times of a saturated transistor. The first set of equations defines the rise, storage, and fall times at a single operating point where the transistor beta, cutoff frequency and collector capacitance are known. The second set of...
This thesis describes the adder to be used with the Galaxy computer, which is to be constructed at Oregon State University.
The need for faster, more reliable adders is discussed
along with previous adder designs related to the
Galaxy Fast Carry Adder.
Both the logical design and circuit design of...
The operation of a tunnel-diode delay-line memory cell is
examined in some detail, and a digital computer program which
approximately simulates the operation of this memory cell is developed.
The data from the computer simulation is compared with the
available experimental data and found to agree very closely for clock...
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 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...
A short history is given of cathode-ray tubes, from the
earliest laboratory tubes available during the early 1900's through
present day high performance tubes. Special attention is paid to
the development of post-deflection acceleration types especially
band-type PDA tubes and an improvement on that type known as the
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.
A set of circuit analysis programs designed for the IBM 1620
computer (having 40,000 digits of memory) is described and its operation
is explained. The set consists of d-c, a-c, and transient analysis
The d-c and a-c analysis programs provide the branch current
and node-to-reference potential for linear circuits....
