Notes/Equations
  1. This model is used to delay the input signal by a certain time interval set by the Delay parameter. It is used in channel impulse response model based on a tapped-delay line model.
    Each firing, Max(64, int(Delay/Tstep)+1) SigOut tokens are produced when the same number of SigIn tokens are consumed, where Tstep is sampling period 1/fs.
