Abstract

The invention relates to a pulse technique and can be used to implement various logical functions of two, three, four, and five variables. The purpose of the invention is to enhance the functionality and scope by ensuring the implementation of threshold logic functions of two, three, four and five variables. The multifunction logic module contains the first and second switches "1 of 8", the address inputs of the same name of which are interconnected and connected respectively to the first, second and third inputs of the variable settings, the logical element NOT, the logical element 2IL, the fifth input of the variable settings and the output of the multifunction logical module Four threshold control buses, four logic gates 2I and four logic gates 2 OR are additionally introduced into it to reach the target. Information signals are sent to the address inputs of the switches, as well as to their gate inputs directly and through the element NOT. Control elements are sent to the AND and OR elements. 1 ill. 1 tab.

If the inputs 5 - 7.9 and 10 instead of certain variables X are applied - constant (zero and single) logical potentials, then depending on the logical potentials applied to the buses 19-22 at the output 4 of the module, different logical functions of one, two are formed , three and four variables (table).

Thus, a multifunctional logic module allows realizing all five possible threshold functions of five variables, as well as logical functions of one, two, three, and four input variables, which testifies to its wide functionality and field of application.
