Solve each of the following 4-bit subtraction problems using 2's complements
representation.
i.
(00110)2-(00101)2
ii.
(0111)2-(0001)2
Solution.
Q2.
What is difference
between minterm and maxterm? Express the following function:
F(x,y,z)=(x+y)z
in the form of minterm and maxterm.
Solution.
Minterm: Each row of a truth table can be associated with a minterm, which is a product (AND) of all
variables in the function, in direct or complemented form. A minterm has the

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 interconnection of these devices may be found in a
shift register, a counter, or in a variety of MSI and LSI packages. With the
introduction of memory elements as components in digital
Q6.
What is difference between Ring Counter and Johnson counter?
Answer.
Ring
counter
A ring counter is a
shift register (a cascade connection of flip-flops) with the output of the last
one connected to the input of the first, that is, in a ring. Typically a
pattern consisting of a single 1 bit is circulated, so the state repeats every
N clock cycles if N flip-flops are used. It can be used as a cycle
