Design a combinational circuit that takes 3-bit pattern as input and outputs binary code of bit position of the first 1' in the pattern reading from MSB (2nd position) to LSB (0th position).An additional output variable V is required along with binary code to indicate that the binary code is valid or note i.e., if the input pattern is '000' then the output V should be '0' to indicate that the binary code is not indicating the bit position of first 1' and we don't care about the binary code if V = 0. Design the required circuit using dual 4x1 MUXS and minimum additional logic.Available resources along with dual 4x1 MUXS are NOT gates, 2-input(AND, OR, NAND, NOR) gates.
