squarewave - generates a square wave with period 2*%pi

Calling Sequence

x=squarewave(t [,percent])

Parameters

• t : real vector, time discretization
• x : real vector, the wave value at each time point in set (-1,+1)
• percent : real positive scalar, the percent of the period in which the signal is positive. Defaut value is 50

Description

squarewave(t) generates the vector of the values of the square wave with period 2*%pi at each date given in the t vector.

squarewave(t,%) generates a square wave such that % is the percent of the period in which the signal is positive.

Examples

t=(0:0.1:5*%pi)';
plot2d1('onn',t,[2*sin(t),1.5*squarewave(t),squarewave(t,10)])
