Q8)lmplement the following FSM using gates and a 'decrementer'. This 'decrementer' is a module which has a clock input and another 2-bit input, and it has a 2-bit output. The function of this decrementer is that: the next state of the device is equal to the input minus 1 modulo 4. For example, if input is 10, the next state output is 01; if input is 00, the next state output is 11. Draw the excitation table (i.e. the table of inputs for the decrementer). Draw the circuit diagram. You can use the decrementer directly and you don't need to implement the decrementer. (15 pt) 0remeW
