    I am not familiar with the characteristic table.

    There are two types of sequential machines.
    1. There is the Mealy machine, where the outputs depend on the state and the inputs.
    2. There is the Moore machine, where the outpust depend only on the state.
    A state table is used for a Moore machine and it shows the 'next' state for every combination of 'inputs' and 'present' state.
    A transition table is used for a Mealy machine to show the 'next' state and the 'outputs' for every combination of 'inputs' and 'present' state.

    Does that help?
