Due Date:Your assignment must be uploaded/submitted before or on 03 Dec, 2012.
Total Marks: 20
Objective:
The objective of this assignment is
to prepare students to familiar with the solution of real life problems using
Boolean expressions. This assignment involves the understanding of mapping
truth table to k-map, deriving Boolean expressions from k-map and finally
implementing simplified Boolean expressions using logic gates
Problem Statement
You have to design an electronic system. In this system you
have four on/off switches S1, S2, S3, and S4 as input and two light bulbs (Red
and blue) on out put as shown in block diagram below.
S1 RED
S2
S3
Blue
S4
This electronic system should work on the following
conditions.
1. Bulb Red should be ON if switches
S1 and S3 are ON
2. Bulb Blue should be ON if
switches S2 and S4 are ON
3. Both the bulbs should remain OFF
in any other condition
“You have to first draw the truth table of whole system
then after calculating the boolean expression for each bulb, draw the circuit
diagram for each bulb”
