tripuls

Sampled aperiodic triangle

Syntax

y = tripuls(T)
y = tripuls(T,w)
y = tripuls(T,w,s)

Description

y = tripuls(T) returns a continuous, aperiodic, symmetric, unity-height triangular pulse at the times indicated in array T, centered about T=0 and with a default width of 1.

y = tripuls(T,w) generates a triangular pulse of width w.

y = tripuls(T,w,s) generates a triangular pulse with skew s, where –1 ≤ s ≤ 1. When s is 0, a symmetric triangular pulse is generated.

Examples

collapse all

Generate 200 ms of a symmetric triangular pulse with a sample rate of 10 kHz and a width of 40 ms.

fs = 10e3;
t = -0.1:1/fs:0.1;

w = 40e-3;

x = tripuls(t,w);

Generate two variations of the same pulse:

  • One displaced 45 ms into the past and skewed 45% to the left.

tpast = -45e-3;
spast = -0.45;
xpast = tripuls(t-tpast,w,spast);
  • One displaced 60 ms into the future, half as wide, and skewed completely to the right.

tfutr = 60e-3;
sfutr = 1;
xfutr = tripuls(t-tfutr,w/2,sfutr);

Plot the original pulse and the two copies on the same axes.
