PART C (Analysis of a Synchronous Counter). External Input X 0 0 0 0 1 1 1 CLK Q1 0 0 1 1 0 0 1 1 Present State Figure 2 1) Built circuit in Figure 2 in DEEDS. Please complete the circuit until it can work as a counter. 2) Investigate the behaviour of the counter by observing the next state of the counter for all combination of Present State and X values. Complete the NextStats, table of the counter in Table 3. Qo 0 1 0 1 FRO 0 1 1 & 0 1 Opc K. 9. FFI Table 3 4 Q1+ 9 Next State Z QO+ External Output Z
3) Produce the equations for JO, KO and JI, KI. 4) Fill out the Transition and Next State Table in Figure 4 based on your equations in Q3. External Input X 0 0 0 0 1 1 1 1 Present .

If they are not, please check your circuit or your equations. 8) What is the function of switch X in the circuit? 10) List all the characteristics of this counter. External Output Z 6) By referring to the Next-State in Table 3, sketch the state diagram of the counter. Please indicate input/output for each transition. 7) What is the main indicator to decide that the counter is a synchronous counter? 9) What were the missing wires that were not drawn in the original Figure 27 What are their functions?
