Question

(a) Design a 2 - digit BCD number -to- binary number converter circuit by using 4 bit parallel adders.
(b) Design a parallel binary multiplier that multiplies a 4- bit number B = B3B2B1B0 by a 3- bit number A = A2A1A0 to form the product C = C6C5C4C3C2C1C0.

Answer 1

SOLUTION: ( b )

In this question we use AND gate for multiplication and use 4 bit adder for adding AND gate output .....firstly we use AND gate and multiply the multipliers A= A2A1A0 to multiplicand B= B3B2B1B0...Than we use two 4 bit adder to design a parallel binary multiplier
