SquareWave

A function whose graph is a square wave.

Syntax

• SuqareWave(x)

  • x is a real number

Description

SquareWave(x) is a square wave with amplitude 1 and wavelength 2⋅π. The range is [−1, 1] and the function transitions from −1 to +1 at x = 0. The value at each transition is 0. Hence,

SquareWave(x) = sgn(sin(x))

(except for numerical issues).
