This simulation demonstrates a ring oscillator, a classic example of how oscillation can be created using only inverting stages and feedback. At the bottom, you can see an odd number of inverter blocks connected in a closed loop. Because the total loop inversion is odd, the circuit can never settle into a stable logic state. Any small change or noise keeps propagating around the loop, forcing continuous transitions between high and low levels. At the top, the waveforms show how each stage output
