The phase lag depends on the frequency of change of the input, and goes to zero as the frequency decreases.
Conversely, the right-handed transmission lines are a low-pass filter with phase lag.
The resulting phase lag in voltage is identical for both energy storage mechanisms, making them indistinguishable in a normal circuit.
For systems hinged at the axis of rotation ( in our case, a semi rigid flapping type rotor head) the phase lag is 90 degrees.
In federal mapping and names collection efforts, there is often a phase lag where a delay occurs in adoption of a locally-used name.
The lag compensator provides phase lag at low frequencies which reduces the steady state error.
In modern helicopters, the input is mechanically translated 90 degrees to compensate for phase lag and to render such turns more intuitive.
In addition, sensory feedback from the environment may contribute to resultant phase lag.
Viscoelastic polymers have the characteristics in between where some phase lag will occur during DMA tests.
Let be the phase lag:
