What is the difference between characteristic table and excitation table in a flipflop?
A characterisitic table has the control input (i.e., D or T) as the first column, the current state as the middle column, and the next state as the last column. Basically, it tells you how the control bit affects the current state to produce the next state. An excitation table has the current state as the first column, the next state as the second column, and the control bit as the third column. Basically, think of this as the state you have (first column), the state you want (second column), and what you must set the control bit (third column) to get the desired state you want. The excitation table is used to implement an FSM.
