Detect upper bound envelope or lower bound envelope.
<dd><b>
Error Number Counter 
</b>
Count number of differences between two signal at 
trigger pulses
<dd><b>
Mean and Std 
</b>
Running mean and standard deviation of the scalar 
input
<dd><b>
Mean and Variant 
</b>
Running mean and variant of the scalar input

Min/Max Index
</b>
Outputs the index minimum (or maximum) element 
in the input vector signal
<dd><b>
Modulo
</b>
Compute the modulo of the input signal
<dd><b>
Modulo Integrator
</b>
Integrate the input signal with modulo calculation for 
the integration state
<dd><b>
Number Counter 
</b>
Count the clock pulse number
<dd><b>
