In the aerodynamics of rotorcraft like helicopters, phase lag refers to the angular difference between the point at which a control input to a rotor blade...

In electronic amplifiers, the phase margin (PM) is the difference between the phase lag φ (< 0) and -180°, for an amplifier's output signal (relative...

enhances the responsiveness and stability of the system. The lag compensator provides phase lag at low frequencies which reduces the steady state error. The...

between stress and strain, where strain lags stress by a 90 degree ( π / 2 {\displaystyle \pi /2} radian) phase lag. Viscoelastic materials exhibit behavior...

Jet lag, or desynchronosis, is a temporary physiological condition that occurs when a person's circadian rhythm is out of sync with the time zone they...

four different phases: lag phase (A), log phase or exponential phase (B), stationary phase (C), and death phase (D). During lag phase, bacteria adapt...

attenuation and the phase lag of the unsteady aerodynamic forces compared to the quasi steady analysis (which in theory assumes no phase lag). Reduced frequency...

than pitching backwards as one might naively expect, because of phase lag. Phase lag is a property of all rotating systems acted upon by a periodic force...

Delayed sleep phase disorder (DSPD), more often known as delayed sleep phase syndrome and also as delayed sleep–wake phase disorder, is the delaying of...

characteristics in between where some phase lag will occur during DMA tests. When the strain is applied and the stress lags behind, the following equations...

cause the output signal to lag behind the input signal by up to 90° for each pole they create. If the sum of these phase lags reaches 180°, the output signal...

research team in China announced that it had produced measurements of the phase lag of Earth tides during full and new moons which seem to prove that the...

band may controlled the Earth's oblateness changes and the obliquity phase lag estimated to be <5.0 kyr, explain obliquity’s damping by the obliquity-oblateness...

configuration), the current in C1 to C2 would be exactly equal, but out of phase, requiring no current from the amplifier or voltage gain from the amplifier...

new focus on shared activity between rhythms including phase synchrony (coherence, phase lag) and magnitude synchrony (comodulation/correlation, and...

{\displaystyle s_{\scriptscriptstyle N}(x)} as follows: Fourier series, amplitude-phase form Fourier series, sine-cosine form Fourier series, exponential form The...

and the phase lag of the color signal with respect to a certain reference which is called colorburst represents the hue; i.e., each phase lag is assigned...

units. The phase lag is ϕ = − Arg ⁡ ( Q ( i ω ) / P ( i ω ) ) {\displaystyle \phi =-\operatorname {Arg} (Q(i\omega )/P(i\omega ))} . The phase lag has units...

strains and the stresses will be perfectly in phase. For a purely viscous fluid, there will be a 90 degree phase lag of strain with respect to stress. Viscoelastic...

hysteresis is a lag between input and output. An example is a sinusoidal input X(t) that results in a sinusoidal output Y(t), but with a phase lag φ: X ( t )...
