1. A combinational circuit has four inputs and one input. The The output is equal to 1 when I. All the the in input puts are are equa equall to to 1 (o (or) II. II. None None of the the inpu inputs ts are are equa equall to 1(or 1(or)) III. III. An odd odd no. no. Of inpu inputs ts are are equ equal al to 1. a) Find the simplified output function in sum of products. b) Find the simplified output output function in product product of sums. 2. esi!n a combinational circuit that accepts a three"bit number and !enerates an output binar# number equal to the square of the input number. $. It is necessar# to multipl# two binar# numbers% each two bits lon!% in order to form their product in binar#. &et the two number be represented b# a 1% a ' and b1 % b'% where subscript ' denotes the least si!nificant bit. a) etermine etermine the the number number of outpu outputt lines lines required. required. b) Find the simplified oolean oolean epressions for each output. output. *. +epeat problem $ to form the sum (instead of the product ) of the two binar# numbers. ,. esi!n a combinational circuit with four input lines that represent a decimal di!it in - and four four output lines that !enerate !enerate the /s complement of the input di!it. 0. esi!n a combinational circuit whose input is a four bit number and whose output is the 2/s complement of the input number. . esi!n a combinational circuit that multiplies b# , an input decimal di!it represented in -.
