ELECTRONICS SYSTEM DESIGN

SUBJECT CODE: EC-502

Paper ID: [E0562]

Time: 3 Hours                                                     Maximum Marks: 100

Instruction to Candidates:

1.     Attempt any Five questions.

2.     All questions carry equal marks.

Q1,

(a)  Design a three input circuit whose output is high when odd number of  inputs is high.

(b) Implement the function f = using QM method.

Q2. Using the design steps required to design a synchronous sequential circuit, design a sequential circuit which samples an input line X(H) three times on each rising edge of system clock (CLK). This system is to generate an output Y(H) only if sequence 110 is detected. The circuit returns to initial state on the rising edge of the third clock pulse.

Q3. Discuss in detail the design phases of a system controller?

Q4.

(a)  Write not on indirect addressed multiplexer configurations?

(b) With examples describe various methods of converting a flow chart into MDS diagram.

Q5. With the help of an example, describe the design steps required to design an asynchronous circuit.

Q6. Design a synchronous counter which counts in the sequence 2, 5, 4, 6, 7, 2. Also analyze your circuit for any hang up state.

Q7. Design a PD flip-flop specified by the following operational table:

P	D	OPERATION
0	0	Changes with clock only If Q=1
0	1	Changes with clock only If Q=0
1	0	Always sets with clock
1	1	Remainsunchanged

Also convert this flip flop into a standard JK flip flop.

Q8. With an example, explain MEV approaches into asynchronous design.
