Design seven segment display circuit for given BCD number using Logisim

 7- Segment Display

In this practical, we are taking 4-bit input to display the BCD number.

As per binary equivalent, we get a BCD output in out 7 segment display is our aim for
this practical.

Truth table:

Logic Circuit:

Boolean Expression for each output(Using K-Map):

a: A’B’D’ + A’C + A’BD + AB’C’

b: A’B’ + A’C’D’ + B’C’ + A’CD

c: B’C’ + A’D + A’B

d: A’B’D’ + A’B’C + A’CD’ + A’BC’D + AB’C’

e: B’C’D’ + A’CD’

f: A’C’D’+ A’BC’ + A’BD’ + AB’C’

g: A’B’C + A’BC’ + A’BD’ + AB’C’

Conclusion:

After performing this practical I am able how to design 7 segment display.
