Detailed Description

A Random value adder operator.

This CDP operator can be used to add a uniformly distributed random number to output. This can be useful to imitate input signal noise in test systems (for example Sine+Random).

F.e. AddRandom with arguments Lower=-1.0 and Upper=1.0 will add random number between -1...1 to signal at every calculation cycle.

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.

Lower and Upper argument can be routed from another signal, parameter or property.

Example

Below is example plot with Sine signal (cyan) and the same signal with operator AddRandom(Lower=-0.1, Upper=0.1) applied (orange):

Actual Processing Code of the AddRandom

unsigned int AddRandom<T>::Process()
{
  if (!d->lower || !d->upper)
    return STATUS_SIGNAL_FAULT;

  std::uniform_real_distribution<double>unif(static_cast<T>(*d->lower), static_cast<T>(*d->upper));
  T random = unif(d->re);
  m_output = static_cast<T>(m_input) + random;

  return STATUS_OK;
}
