Webb30 sep. 2016 · 1. Hi i have derived the following SoP (Sum of Products) expression , by analyzing the truth table of a 3 bit , binary to gray code converter. I ask for verification, because i feel as though this answer may not be correct or complete. X = a'bc' + a'bc + ab'c' + ab'c. which, using k-maps, was simplified to. X = ab' + a'b. WebbTo evaluate a variable expression means to find the value of the expression when the variable is (or variables are) replaced by a number (or numbers). Here is a variable expression: #3x+7# . To evaluate this expression when #x = 2# mean to substitute #2# in place of #x# , and find the number (the value).
