Q2
Explain the rules for simplifying functions using Karnaugh maps. 10 10
Answer.
he Karnaugh map uses
the following rules for the simplification of expressions by grouping together adjacent
Q.3.
Expand the following Boolean functions into their canonical form: [5+5] =10
ANS:
Canonical forms
express all binary variables in every product (AND) or sum (OR) term of the
Boolean function. There are two types of canonical forms of a Boolean function.
The first one is called sum-of product and
Q4.
Simplify the following Boolean function:
F = A’C + A’B + AB’C + BC, using K-map?
Answer:
We will use the
Karnaugh map to simplify Boolean expressions by minterm or maxterm values on
the map and then grouping terms to develop simpler Boolean expressions.
Given,
F=A'C+A'B+AB'C+BC
We can
Q5.
What are sequential circuits? Explain differences between sequential circuits
and combinational circuits.
Answer:
Sequential circuits
A digital logic
circuit or system is usually made up of combinational elements such as NAND and
NOR gates and memory elements which may, for example, be discrete flip-flops or
latches. Alternatively, an
