Draw the state diagram for a Modulo-6 synchronous counter which follows the count sequence 000, 010, 011, 001, 100, 110, 000, 010, … . Show all possible states including the ones that are not desired. The undesired states should be depicted to be transiting to any of the desired states. Choose the 000 state for this purpose. It is important to include the undesired states to ensure that, if the counter accidentally gets into any of these undesired states owing to noise or power-up, the counter will go to a desired state to resume the correct sequence on application of the next clock pulse.
