Problem

Create a FSM of a circuit that detects 3 Logic High in a row assuming single input and two states

Process

  1. Create a state diagram. Note transitions are dependent on
  2. Create a State Table
  3. Assign Flip-Flop Note that since there are 8 states, we assign 3 flip flops.
  4. Create the second State Table
  5. Create a K-Map for circuit design
  6. Assemble the circuit from K-maps Product of Maxterms
