Detailed Description

The SignOperator returns 1 when the input is positive and -1 when the input is negative and 0 when the input is 0.

Arguments

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 signal (cyan) and the same signal with SignOperator() applied (orange):

Actual Processing Code of the SignOperator

unsigned int SignOperator<T>::Process()
{
  T inputValue = (T)m_input;
  if (inputValue < 0)
    m_output = -1;
  else if (inputValue > 0)
    m_output = 1;
  else
    m_output = 0;

  return STATUS_OK;
}
