energy-shiftsolvable modelspherical infinite square-well trapThe energy-spectrum of two point-like particles interacting in a 3-D isotropic Harmonic Oscillator (H.O.) trap is related to the free scattering phase-shifts delta of the particles by a formula first published by Busch et al. It is...
The present invention proposes a new way of improving the phase stability and frequency selectivity of a phase shift oscillator (100). By introducing a filter-order enhancing feedback loop (124) in association with a phase shift filter (122) in the oscillator, higher-order phase shift filtering...
The phase rotation of 180° is required due to use in the chain that comprises the oscillator of a real gain amplifier. Thus, using three low-pass or high-pass cells connected to an amplifier, a low-frequency phase-shift oscillator with reduced overall size can be realized, as suggested in...
12 Eqn. 13 where gainu, gainI are calibration gains, θcomp, is the calculated phase shift caused by current transformers, and URMS, IRMS, Q, P are quantities measured by the non-calibrated meter. Contrary to the gain and phase shift calculations that are based on RMS values, the ...
After a delay lock loop synchronizes a reference clock signal with a skewed clock signal, a digital phase shifter can be used to shift the skewed clock signal by a small amount with respect to the ref
35. A proper stimulation can be used to shift the network from an attractor of a synchronized state to that of a desynchronized state, or vice versa. In PD, the desirable therapeutical effect is long-lasting desynchronization that can be achieved using e.g. Coordinated Reset (CR) ...
phase shift is set to exact phase quadrature, which is indicated by a minimum DC level at the output of the mixer. The mixer now works as a phase detector and generates a voltage that is proportional to the phase difference between the two sources. The reference oscillator has a very low...
First-principles calculations show that such a structural rearrangement not only changes the electronic density of states, but also results in significant changes of the transition matrix elements, i.e. the oscillator strength of the optical transitions. The decrease of the oscillator strength in the...
The I and Q signals are vector quantities, so the amplitude and phase shift of the received signal can be calculated using trigonometric identities, as shown in Figure 4. The local-oscillator (LO) input is the original transmitted signal and the RF input is the received signal. The ...
This means that the 90° phase shift between leader and follower controllers gives a 180° phase shift between the currents in the output inductors and hence maximum ripple cancellation. For more information about synchronizing more than two UCC2895x devices, see Synchronizing Three or More UCC...
