| Summary |
"A threshold element (TE) is a mathematical model of a class of logic gates. The desirability of a threshold element in the application of digital systems stems from its richness of logic power and its relative economy. On the other hand, the tighter tolerences required by the threshold logic element as compared to conventional logic gates have prevented them from being utilized extensively. The purpose of this thesis is to propose a versatile threshold element having high noise immunity and loose tolerance requirement. The proposed TE which has variable threshold and mixed weight capability uses current switching to enhance noise immunity and a differential amplifier voltage comparator to obtain the versatility. The threshold of TE can be varied by a digitally controlled signal to generate a wide spectrum of output functions Practical applications of the designed circuit are included along with sensitivity-investigation"--Abstract, leaf ii. |
