Name That Waveform

Every waveform below is a real simulation, produced by the same engine as the playground. Read the timing diagram and name the circuit that made it. One wrong answer ends the run, so how long a streak can you build?

Why it matters

Reading a timing diagram, spotting a counter's halving frequencies, a ring counter's single travelling 1, or an LFSR's pseudo-random churn, is a core skill for debugging real hardware. Every one of these came straight out of the simulator, so you can build and inspect them yourself in the hands-on course or a playground.
