Abstract : Major emphasis is placed on theoretical aspects of threshold functions with particular attention given to synthesis methods for specifying networks of threshold devices. Techniques are presented for determining linear spearability and for calculating weights and threshold for those functions which are linearly separable. Algorithms for partitioning switching functions into sets of threshold functions are described as well as techniques for decomposing networks of unconstrained threshold devices into networks of devices satisfying certain design constraints. Special consideration is given the effects of noise and tolerances in several types of circuits suitable for threshold devices with the primary objective of determining the important design constraints. Logical design examples are presented to demonstrate the general utility of threshold functions. (Author)
