About the Square Wave Signal color outline icon
This icon traces a square wave: a flat baseline that jumps to a tall rounded-corner pulse, drops into a trough and steps back up again. It reads instantly as a digital signal, clock pulse or oscillator output, which makes it useful in audio plugin interfaces, electronics tutorials, synthesizer app toolbars, lab report slides and IoT monitoring dashboards.
The stroke keeps a uniform weight with softly rounded corners, and the two pulses sit at different heights to suggest a repeating cycle rather than a single event. It sits well beside sine, sawtooth and triangle wave icons in an oscillator set. Keep it above 24 px so the vertical risers stay distinct.
This is the colour outline version of the square wave signal icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
