1. Design an Excess-3 (Ex-3) checker circuit for an input of 4-bits. (the output is logic 1 if the input is a valid Excess-3 and is 0 otherwise). 2. Design a logic circuit with an input of 4-bit (ABCD) and one output (Y). The output is logic 1 if the input is less than (4)10, and don't care when the input is greater than (11)10.
