About the Wave Square Step Signal black outline icon
A single continuous line turns at right angles to form a square waveform, stepping down, rising to a tall peak, dropping to a deep trough and settling on a mid-level plateau with rounded ends. The uneven step heights read as a digital pulse or a discrete signal rather than a smooth curve. Use it in audio editing tools, oscilloscope and test equipment UIs, synthesizer apps, IoT sensor dashboards and electronics documentation.
The three vertical strokes vary in length to break the monotony of a textbook square wave, and the rounded stroke caps soften the hard corners. It pairs with sine wave, pulse and signal bar icons. At small sizes crop to two steps so the corners stay distinct.
This is the black outline version of the wave square step signal icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
