<P> In electronics design, an excitation table shows the minimum inputs that are necessary to generate a particular next state (in other words, to "excite" it to the next state) when the current state is known . They are similar to truth tables and state tables, but rearrange the data so that the current state and next state are next to each other on the left - hand side of the table, and the inputs needed to make that state change happen are shown on the right side of the table . </P> <P> In order to obtain the excitation table of a flip - flop, one needs to draw the Q (t) and Q (t + 1) for all possible cases (e.g., 00, 01, 10 and 11), and then make the value of flip - flop such that on giving this value, one shall receive the input as Q (t + 1) as desired . </P> <Table> <Tr> <Th_colspan="2"> States </Th> <Th_colspan="1"> Input </Th> </Tr> <Tr> <Th> Previous </Th> <Th> Present </Th> <Th> </Th> </Tr> <Tr> <Td> 0 </Td> <Td> 0 </Td> <Td> 0 </Td> </Tr> <Tr> <Td> 0 </Td> <Td> </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> 0 </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> </Td> <Td> 0 </Td> </Tr> </Table>
