Q1. Design a combinational circuit whose input is a 4-bit number and whose output is the 2’s complement of the number.
Q2. Multiply the given pairs of signed 2's complement numbers by using Booth's algorithm:
Multiplicand = 110011 and Multiplier = 101100
Q3. A digital computer consists of a common bus system of 16 registers of 32 bits each. The bus is constructed with the multiplexers.
a) Determine the selection inputs which are present in each multiplexer?
b) Determine the size of multiplexers which is required?
c) Determine the number of multiplexers which are there in the bus?
