question 02. 1. Based on the state diagram, fill in the Present State', 'Input', and 'Next State' columns in the state table below, Present State input Next State Inputs of D-FFs DA Da A B X A B b. Considering the 'Next State' columns, figure out what input values DA, DB, ... must be applied to each flip-flop for each state, and enter these values into the appropriate columns in your state table. 3
4. Draw K-maps for each FF input below and use them to write the Boolean equations for DA, DE, ... in their simplest form For DA: Bx B B For Ds: Bx А A 00 01 11 10 00 01 10 o 0 A 1 A -X DA= Da- d. Draw the required circuit diagram c. Build the circuit using 7474 ICs (D-type flip-flops), plus any needed logic chips. Use the TTL output of the function generator as the clock, use a logic switch for each input variable, and use a logic indicator to show the output state of each flip-flop with FF A at the left.
02. [60 points) Design and build a circuit that implements the state diagram shown in Fig. 1. Use one or more 7474 ICs (D-type flip-flops), plus any needed logic chips. Name the flip flops A, B and name the input variable. This circuit has no defined outputs. D Fig. 1. State diagram for 02.
