An Investigation Of An Electronic Ignition System For Internal Combustion Engines, Richard David Wheat
An Investigation Of An Electronic Ignition System For Internal Combustion Engines, Richard David Wheat
Masters Theses
"Many types of electric ignition systems have been developed, used, and discarded in favor of systems less expensive and more adaptable to internal combustion engines, Two types which might be classified as high-tension, jump-spark systems are in common use today. These two systems are (1) Battery-coil ignition used mainly on automobiles, and (2) Magneto-ignition used extensively on aircraft engines. A considerable amount of work has been done to determine the extent to which the character and intensity of the electric spark affect the ignition process. This work has revealed that a certain minimum amount of energy is required from the …
Analysis Of Cascade Of Four-Terminal Networks, Ernest Randolph Roehl
Analysis Of Cascade Of Four-Terminal Networks, Ernest Randolph Roehl
Masters Theses
"The object of this thesis is to find analytic expressions for the voltage and current variations along a structure composed of a cascade of identical dissymmetrical four-terminal networks driven harmonically at the sending end and working into an impedance at the receiving end and an impedance that can be placed at any of the junctions along the cascade. The method of analysis that is applied is analogous to that used in solving the long-line problem. A transmission system usually consists of the line or cable itself plus numerous other links whose purpose it is to correct defects in the line …
Design And Construction Of An Electronic Gain-Phase Meter, Gabriel G. Skitek
Design And Construction Of An Electronic Gain-Phase Meter, Gabriel G. Skitek
Masters Theses
"There are many communication and electronic circuits, such as filters, phase-shifting networks, matching networks, voltage amplifiers with and without feedback, whose proper usage with associated equipment depends upon the knowledge of the variation with frequency of the voltage ratio and phase angle between the output and input sinusoidal voltages or currents...It is the purpose of this thesis to design and build an electronic instrument that will measure the voltage gain and phase angle between two sinusoidal voltages or current of communication circuits, in such a manner as to aid the student in visualizing how these quantities vary with frequency, and …
A Study Of Cathode Drift Compensation In D-C Amplifiers, Joseph W. Rittenhouse
A Study Of Cathode Drift Compensation In D-C Amplifiers, Joseph W. Rittenhouse
Masters Theses
"The expression, cathode drift, has to do with the random variations in vacuum tube plate current which are attributable to similar variations in emission velocities of electrons leaving hot cathodes. The fact that these random current changes appear to result from spurious drifts in cathode potential, since all other electrode potentials are unrelated to them, give rise to the expression, cathode drift...The problem with which this paper is concerned is a study of some of the possibilities of compensating for cathode drift effects in a single amplifier stage. Specifically, this paper will: (A) present a detailed mathematical and graphical analysis …
