<h2>Initialization</h2>
<p>
<span class="emphasis"><em>initialvalue</em></span> If given, sets the internal
state. Default=0
</p>
</div>
<div class="refsect1">
<a id="idm281472892655576"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>ain</em></span> -- Trigger. Trigger can be any
signal. A trigger happens when the signal changes from
non-positive to positive.
</p>
<p>
<span class="emphasis"><em>kdur</em></span> -- Duration of the trigger in seconds.
</p>
<p>
When a nonpositive to positive transition occurs at the input,
Trig outputs the level of the triggering input for the specified
duration, otherwise it outputs zero.
