A digital circuit accepts binary-coded-decimal inputs (only the numbers from 010 to 910). The numbers are encoded using 4 bits A, B, C, D. The output F is High if the input number is less or equal with 410 or greater than 810. For numbers greater than 910 the output is x (don't care). Complete the truth table for this function. Write the expression for F as Sum-of-Product. Do not minimize the function.
