Unformatted text preview: Question 2: You have learnt how to construct a BCD-to-Excess-3-Code converter in last lecture. Now, instead of using two-level AND-OR circuit, construct (a) A BCD-to-Excess-3-Code converter using a 4-bit full adder only (b) An Excess-3-Code-to-BCD converter using a 4-bit full adder only Question 3: Find the output Boolean functions f 1 & f 2 for the circuit as shown in the following figure, and explain the operation of the circuit. f 1 f 2 a b c...
