Question
Problem 1
execute following Boolean functions with the appropriate multiplexer and external gates
F1= sum 1,3,4,11,12,13,14,15
F2=sum 1,2,5,7,8,10,11,13,15
Problem 2
execute the Boolean functions described in Problem 2 with a 4x1 multiplexer as building block. You can use external gates too.
Problem 3
plan a code converter circuit that converts a decimal digit from 8, 4, -2, -1 code to BCD code.Apply the circuit using AND, OR and NOT gates.
Problem 4
plan an excess-3-to-binary decoder using the unused combinations of the code as don't care conditions.
