01 [40 polts) Design and build a ripple counter that counts from all the reports Revell that a ripple counter is an asynchronour counter bon Tip-flops shown below LIV RE . CIN CIH Clearin 4. Draw a circuit diagram below, implementing a ripple counter that counts from 0 to 11. then repeats. Use 7476 (JK flip-flop) and 7400 (NAND) ICs. Include pin numbers and make sure to show every necessary connection b. Build the circuit using 7476 and 7400 ICs. Use a pushbutton as the input clock, and connect LED indicators to show the counter output, with the MSB at the left. Keep your circuit from Q1 in place as you complete 02 below. 2

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 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

e. Draw K-maps for each FF input below and use them to write the Boolean equations for DA, DA,..., in their simplest form. For DA: Bx А B B 00 01 11 10 For D Вх А 0 00 01 11 10 0 A 1 A[: DA= Ds 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
