(Electronics & Computer Engineering)
Time: 3 hours Max Marks: 80
Answer any FIVE Questions
All Questions carry equal marks
? ? ? ? ?
1. (a) Explain the cubical operations Sharp, disjoint Sharp, Disjunction, Adjacency.
(b) Find the CAMP-II printout for the function
f (abcd) = P ( 2 - 8 , 10 - 13 , 15 ) [8+8]
2. (a) Draw an ASM chart for a circuit with two 8-bit registers RA and RB that
receive two unsigned binary numbers and perform subtraction operation RA
RA-RB and set a borrow flip flop to 1 if the answer is negative.
(b) Write short notes on hardware description languages. [8+8]
3. List the PLA programming table for the BCD to Excess-3 code converter. [16]
4. (a) Describe the Boolean difference method in a combinational circuit.
(b) Find the test set to detect A1- SA0 and A1- SA1 faults using path sensitization
method.
5. (a) Define the term fault tolerance of a system?
(b) How many difference approaches are there to have fault tolerance of a digital
system? Explain about one such approach. [4+12]
6. An unknown three state machine with two input symbols 0 and 1 is provided with
the input sequence X, and it responds by producing the output sequence Z,
X 1 1 0 0 1 0 1 0 1 1 1 1 1 0 0 0 1 1 0 0 1 0 1
Z 1 0 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 1 1 1 0 0 0
Show that this experiment is sufficient to identity the machine uniquely. [16]
7. (a) Discuss the types of faults in PLAs.
(b) Minimize the following function implemented on PLA using IISC algorithm.
f = 2120 + 0102 + 1121 + 0002 [8+8]
8. (a) Explain folding theorem. What are the necessary and required conditions to
fold a PLA along the column to have maximum folding?
(b) Write short notes on the test generation for the faults in PLA
