Description
~~~~~~~~~~~

It is a discrete block. The block outputs a periodic scalar piecewise
constant signal. Signal begin at **Initial State** value. The output
is incremented when block received an event on its activation input
until output reaches the **Upper Limit** parameter value. At this time
the output is reset to 0. For a periodic event input, the output is a
quantized sawtooth signal.



Data type
~~~~~~~~~


+ Output: scalar double.




Dialog box
