🔍 Key Concepts

• How a JK flip-flop behaves when J = K = 1 (toggle on each triggering clock edge) • In a ripple counter, each flip-flop output frequency is a divide-by-2 of its clock input • Using the timing diagram to see how many clock pulses are needed for one full cycle of Q3

💭 Think About

• From the waveform section (B), count how many clock-input pulses it takes for Q0 to complete one full on-off cycle. How does that compare to the clock frequency? • Then see how many Q0 cycles make one Q1 cycle, how many Q1 cycles make one Q2 cycle, and so on up to Q3. • Once you know how many input clock pulses correspond to one full Q3 cycle, use that number to find the output frequency when the input is 2 kHz.

✅ Before You Answer

• Verify that each flip-flop is clocked by the previous Q output, not directly by the original clock, confirming a ripple (asynchronous) counter. • Confirm from the diagram that each stage’s frequency is exactly half the previous one (check Q0 vs clock, Q1 vs Q0, etc.). • Before choosing an answer, compute: input frequency ÷ (total division factor from FF0 to FF3) and check it matches one of the listed choices.
