🔍 Key Concepts

• Identify the symbol used for each of the four blocks labeled FF0–FF3 and note the J and K inputs with Q outputs • Think about what type of digital device toggles its output state on clock pulses and can be cascaded to form binary counters • Compare the waveform diagram (Q0–Q3) to the typical output of sequential storage elements such as latches, gates, or counters

💭 Think About

• Look at how each block responds to the clock input and how its Q output changes relative to the others—does this behavior match logic gates, amplifiers, or storage elements? • Ask yourself which one of the options is normally driven by a clock and produces divided-down square waves like Q0, Q1, Q2, and Q3 • Consider whether exclusive OR gates or op amps by themselves would produce the stepped counting pattern shown in the timing diagram

✅ Before You Answer

• Confirm which listed device type normally has labeled inputs J and K with an output Q • Verify which device is typically used in series to build binary counters or frequency dividers • Rule out options that do not require a clock signal for their basic operation
