Abstract : A threshold element is a mathematical model of certain types of logic gates and of a biological neuron. Much work has been done on the subject of threshold elements with fixed thresholds; this study concerns itself with elements in which the threshold may be varied, variable-threshold threshold elements. Physical realizations include resistor-transistor elements, in which the threshold is simply a voltage. Variation of the threshold causes the element to realize varying Boolean functions. The dissertation considers in depth the nature of the set of functions generated by a single variable-threshold threshold element as the threshold is varied and by a net of such elements, and methods of synthesizing a given set of functions by a single element or a net of elements.
