Detailed Description

MovingDelta operator that calculates delta (i.e. difference between min and max) of the input values in the given time window. For signed values the MovingDelta sign also indicates the the delta sign - the delta is positive when the minimum value was found earlier in the history than the maximum, and is negative otherwise.

Arguments

Properties

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Example

Below is an example plot with Sine(Period=10) signal (cyan) and the same signal with MovingDelta(Time=0.´5) applied (orange):

Actual Processing Code of the MovingMaximum

unsigned int MovingDelta<T>::Process()
{
  auto windowSize = d->valueHistory->GetWindowTime();
  if (windowSize < 0.0)
  {
    GetParent()->ReportConfigurationFault(this, "Negative window Time");
    d->faultReported = true;
    return STATUS_SIGNAL_FAULT;
  }

  if (d->valueHistory->GetReset())
    d->valueHistory->Reset();
  d->valueHistory->PushValue((T)m_input);
  m_output = d->CalculateDelta();

  return STATUS_OK;
}
