Question

Q5. There are four states (S0, S1, S2, S3) in a state machine corresponding to numbers x2, y1, z0, and 43, respectively. Here x, y and z are digits of your registration number; e.g. if the registration number is 785 then x = 7, y = 8, z = 5 and the numbers are 72, 81, 50 and 43. If the machine is at a state, which represents the highest number then if the input is 0 the machine transits to state representing the 2nd smallest number and if the input is 1 it remains in the same state. Likewise, if the machine is at a state, which represents the smallest number then if the input is 1 the machine transits to state representing the 2nd highest number and if the input is 0 it remains in the same state. At any other state if the input is 0 the state transits to a state that represents the next lower number and if the input is 1 the state transits to a state that represents the next higher number. You are provided with T FFs and external gates. a) Draw the state diagram. b) Tabulate the state table. c) Derive the state equations. d) Synthesize using JK FFs e) Draw the logic diagram of the circuit.
