we wish to design a 4-bit binary-coded decimal (BCD) input/single output logic circuit that will be used to distinguish bits that are greater than or equal to 5 from those that are less than 5. The input will be the BCD representation of the decimal digits 0. 1,2,... . 9, and the output should be 1 if the input is 5, 6,7, 8, or 9, while the output should be 0 if the input is less than 5. A suggestion would be to write down the truth table for this logic function, and a requirement is to simplify the logical expression for the output as much as possible. (Hint: beware of don't care conditions). #9, #10. Find the minimum equivalent logic circuit for the schematic shown below. LG
