The Input signal is delayed by a given time instant, or more precisely:

y = u(time - delayTime) for time > time.start + delayTime
  = u(time.start)       for time ≤ time.start + delayTime

where delayTime is an additional input signal which must follow the following relationship:

0 ≤ delayTime ≤ delayMax
