Triangle wave test signal


triangle(x) creates a triangle wave with a period of 1 and range -1 to 1. In the interval 0 <= x < 0.5, triangle(x) increases. The difference between triangle waves and sawtooth waves is that a triangle wave has equal rise and fall times.

Sample triangle signal

To specify the number of triangle wave cycles within a test step, use this operator with the elapsed time (et) operator.


Create a Triangle Wave
