# Lab 3 - Exercise 1

## Question

1. Y=1 if A(MSB) B C D(LSB) = 1, 2, 4, 5, 6, 7, 8, 9, 11, 12, 13 else 0. Identify the Boolean logic for Y & Implement the same in WOKWI tool.

## Solution

* Final Expression after solving K-Map is `Y = A'.B + A.C' + C'.D + A.B'.D + A'.C.D'`, which is implemented here using logic gates.
