a) Design the doubler circuit shown in Figure 2, for which:D = d8 d4 d2 d1 and B = b8 b4 b2 b1

are each an 8421 BCD code digit. The circuit must implement the equation:

10C* + B = 2D + C
Where C* = 0 if and only if 2D + C is less than 10.

b) Can three of these doublers be interconnected to form an iterative circuit which will double a three digit number expressed in 8421 BCD code?
