Use logical tables verify the validity of the term:
Write the logical table for the function of four variables, where Y = 1, where only two inputs is 0, find a mathematical expression using Karnaugh maps.
Write a logical table for the function of the three variables, where Y = 1 if simultaneously on at least two inputs a value of 1, find the mathematical expression using Karnaugh map.
Write the logical table for the function of four variables, where Y = 1, if currently only three inputs a value of 1, find the mathematical expression using Karnaugh maps.
