QUESTION 2 Ali wants to observe the effect of cascading between synchronous CTR DIV 4 and asynchronous 74LS93 CTR DIV 16 counter circuits. He cascaded both circuits as shown in Figure 2. Based on the figure, help Ali to observe the effect by filling in the truth table as shown in Table 2. High External clock CTEN CLK synchronous CTR DIV 4 Q₁ TC Figure 2 TIL asynchronous 74LS93 CTR DIV 16 CLK A CLK B RO(1) RO(2) Qo Q1 Q2 Qs
CLK Initial 1 2 3 4 5 6 7 00 8 9 10 Outputs of synchronous CTR DIV 4 Qo 1 Q₁ 0 Table 2 Qo 0 Outputs of asynchronous CTR DIV 16 74LS93 Q₁ 0 Q₂ 0 Q3 1 (30 marks)
