Robotics
This block is a event-driven square wave generator. It lets you adjust amplitude (A), period (P), impulse width (W), bias (B) and delay (D).
This block has one regular output. First pulse evaluation is done according to the following law: if t >= D pulse is ON, i.e.
-
y(t) = A + B, when t <= W
-
y(t) = B, otherwise
if t < D pulse is OFF, i.e. y(t) = 0.
Pulse repeats itself every P seconds.
