square waves
On-off signal pattern
Square waves are waveforms that alternate abruptly between two levels, producing a rectangular shape when graphed—unlike the smooth curves of sine waves.
In electronics and audio synthesis, square waves create a distinctive hollow, buzzy tone rich in odd harmonics.
Square waves also name a dangerous ocean phenomenon where two wave systems cross at right angles, creating a checkerboard pattern on the water's surface that can be hazardous to swimmers and boats.
