It is proved that in the algebraic normal form of the strict majority logic function with order n = 2m + 1(w > 1), all the nonlinear terms of k-th order, (n + 1)/2≤k≤n-1, must appear. Threrfore, from the view of cryptology, such strict majority logic function has good characteristics.
At the present time,more and more research has been focused on the expression of logic function in Reed-Muller domain and the conversion methods between SOP and Reed-Muller expression,POS and dual form of Reed-Muller expression.
目前,很多研究着眼于任意逻辑函数在Reed-Muller领域中的表达方式和SOP与规范Reed-Muller展开式之间,POS与Dual Form of Reed-Muller展开式之间进行转换。
Finally,we especially list the design and implementation scheme of some important LFB,as the GRE logic function block--CheckGREHeader,GREEncap,StripGREHeader and the logic function block for distribution operation--Splitfirst.
INTERLOCK117 is an interlock logic which protects TA drying and conveying on system devices in PTA plant. The design requirements,design plan,logic function implement and improvement of INTERLOCK117 on DCS were introduced.
The corresponding coupling delay tests detect all robust path delay faults in any realization of a logic function.
We present two design methods that produce concurrently testable and cascadable combinational blocks for a given logic function.
A method is proposed for transforming the state table of a logic function into a minimum disjunction-conjunction formula of a multiplexer followed by its decomposition into standard multiplexer formulas.
A logic function with PLA format is represented as an OBDD form first.
The macromodular behavioral technique combines multiple-logic function macromodeling, functional latency and nested macromodel.
Based on the principle that any arbitrary symmetrical ternary logic function may be expanded into a sum of minterms in the canonical form, this paper introduces the conception of a truth matrix. The basic rules of logic operations of truth matrix are defined. Application of truth matrix to analyze a logic circuit is intuitive and simple, and the results may lead to the derivation of some identical relations of certain symmetrical ternary logic system.
In this article thirteen theorems of connection and manipulation for mixed logic, which cover complete sets of logic functions, are presented. Thus the conventional logic design may possibly be replaced by the mixed logic. In the course of theorem proving, DeMorgan theorem and Shannon theorem are also generalized.
The paper discusses the design of part relay logic circuits which are in the control system of a certain pilotless aircraft & presents the method of writing & simplifying the logic function with Truth table & Karnaugh map. And the logic circuit is shown in the figure.
