We have a 7 segment decoder circuit that can display different numbers and alphabets when different inputs are applied. We also can generate some error bits on 7 segments which don’t occur with the specific input code. Your task is to generate random alphabets like “DLD PAPER”.  You can take inputs from 0 to 7 as there are 8 different alphabets in given data.

Steps needed: Truth Table for three variables, SOP simplification through K map for ONLY outputs b, e and f, Equation and circuit
