WebThe delay component is important because, unlike the Isolator, it will calculate without having a signal at the input port. If the laser and the delay calculate, the Isolator will have signals available at both input ports. Run the simulation again and open the visualizers. Figure 3: Basic bidirectional system using a delay. Viewing the results WebOften the group delay is nothing more than the phase delay. This happens when the phase delay is independent of frequency. But when the phase delay depends on frequency, then a completely new velocity, the ``group velocity," appears. Curiously, the group velocity is not an average of phase velocities.
