Question: Using adders, combinational building blocks, and gates, design a circuit that accepts a four-bit 2s complement binary input a(3 downto 0) and outputs a seven-bit

Using adders, combinational building blocks, and gates, design a circuit that accepts a four-bit 2’s complement binary input a(3 downto 0) and outputs a seven-bit 2’s complement output b(6 downto 0) that is five times the value input. You cannot use a multiplier building block. Use the minimum number of adder bits possible.
