This simulation shows how a pulse counter works step by step using signals and LEDs. At the top, the square waves are simulated clock pulses. Each pulse is one event to be counted. Every time the clock signal rises, the counter moves forward by one count. Faster waves show the input clock, and slower waves show how the counter outputs change over time. In the middle, the counter block has outputs labeled 1, 2, 4, and 8. These are binary outputs. The 1 output changes on every pulse. The 2 output
