A multifunctional module for implementing non-repetitive functions of four variables operates as follows. Signals XI and X2 are fed to inputs 1 and 2 of element 9. The signals XZ and X4 are fed to the inputs 3 and 4 of the elements AND 10 and OR 11. From the element AND 9 the signal goes to the inputs of the element OR 16, And 17, And 15. And from the element OR 11 the signal goes to the element And 18. The signal X1 is sent input 2 and element 15.
