sawtooth

Sawtooth wave test signal

Syntax

y = sawtooth(x)

Description

y = sawtooth(x) creates a sawtooth wave from the input x based on the equation,

$$2\left(x-\lfloor x\rfloor -\frac{1}{2}\right),$$

where the L-brackets represent the floor of the contents. The output wave has a range from -1 to 1. Use the et operator as the input to generate the wave throughout simulation time in the test step. Divide et by a value to specify a period. Use the sawtooth operator in the test step of a Test Sequence or Test Assessment block.

Examples

Create Sawtooth Wave

In a Test Sequence block, create a sawtooth wave with a period of 5.

The Test Sequence block outputs the sawtooth wave:

Input Arguments

x — Value during test step

numeric scalar

Value during the test step, specified as a numeric scalar.
