Implementation using D flip flop - mbits-mirafra/digitalDesignCourse GitHub Wiki

Step 1: Draw the state diagram

There are 3 states:

  • 0-00

  • 1-01

  • 2-10

Step 2: Draw the State Table

Since there r only 3 states the 4th state 11 is represented with -

Step 3: Excitation Table for D flip flop

Step 4: Excitation Table with Flip flop inputs

Step 5: Considering the present state and the input, find the equations using Kmap

The Karnaugh maps for simplifying flip-flop inputs and the output are shown below

K Map for DB

Kmap1

Db_EXP

K Map for DA

Kmap2

Da_EXP

K Map for output Y

Kmap3

Y_EXP

Step 6: Design the Circuit
