ABSTRACT:
Gates or switches for use in circuits implementing ternary and multi-value functions are disclosed. The gates can be optical, mechanical or electrical. The gates can conduct or not conduct when a control input assumes one of multiple states, or when a control input assumes two or more of multiple states. Circuits and methods for implementing ternary and multi-value functions are also disclosed. Corrective design techniques that can be used when a logic expression is incorrectly realized are also disclosed. Circuits that use inverters and gates to realize logic expressions are also provided.
