-/**
- * SchmidtTrigger unit.
- * <P>
- * Output logic level value with hysteresis. Transition high when input exceeds setLevel. Only go
- * low when input is below resetLevel. This can be used to reject low level noise on the input
- * signal. The default values for setLevel and resetLevel are both 0.0. Setting setLevel to 0.1 and
- * resetLevel to -0.1 will give some hysteresis. The outputPulse is a single sample wide pulse set
- * when the output transitions from low to high.
- * 
- * <PRE>
- * if (output == 0.0)
- *     output = (input &gt; setLevel) ? 1.0 : 0.0;
- * else if (output &gt; 0.0)
- *     output = (input &lt;= resetLevel) ? 0.0 : 1.0;
- * else
- *     output = previous_output;
