摘要： A control circuit for a feed forward amplifier provides for pausing control and continuous adjustment of a control signal, provides for the control signal to start at any point, provides for rapid convergence, and that does not perturb the system up or down one step to confirm the convergence of the system. The control circuit receives a sampled version of a feed forward amplifier output signal, generates a non-offset control signal based on the sampled output signal, separately generates an offset voltage by reference to voltages stored in a table or based on the non-offset control signal, and combines the non-offset control signal with the offset voltage to produce a control signal. The feed forward amplifier may then adjust an error signal based on the control signal to produce an adjusted error signal that is capable of reducing distortion in the feed forward amplifier.

摘要： The invention relates to a method for calculating parameters fro frequency and/or amplitude modulated electromagnetic pulses for adiabatic transfer steps in a quantum mechanical system. The dynamic steps of the quantum mechanic system comprise a Hamilton Operator (H(t)) of a current system of co-ordinates. The inventive method consists of the following steps: a) transformation of the Hamilton Operator (H(t)) of a current system of co-ordinates into a subsequent system of co-ordinates for describing the t time depandency of the change in direction of the Hamilton Operator (H(t)); b) determination of the automatic commutation of the Hamilton Operator (H(t)) at a time t and the Hamilton Operator (H(tnull)) at a time tnull in the corresponding system of co-ordinates, whereby a differential equation system is obtained; c) calculation of the parameters from the differential equation system thus obtained.

摘要： The invention relates to the determination of a physical property as a function of a n-dimensional domain, with n being a natural number. Values of said physical property correspond to vertices of a n-dimensional first grid that represent the domain. For a set of cells of said first grid, at least one inner point per cell is determined, whereby said inner points, together with the vertices of the first grid, form a respective second grid. Then, for each of said inner points, a corresponding value of the physical property at said inner point is determined, whereby in case a predefined criterion is not fulfilled, said value at the inner point is obtained by performing a measurement.

摘要： A delay mismatched feed forward amplifier system employing a control system and method using floors and penalties is disclosed. The disclosed control system and method allows the second loop phase adjuster setting to be offset in a repeatable and controlled manner. Applying floors and penalties to offset the steady-state phase adjuster setting modifies the conventional pilot cancellation approach. In the conventional case, pilot cancellation has a distinct minimum that corresponds to the desired adjustment setting. In the disclosed approach, the measured pilot cancellation is clipped to a lower bound or floor to produce a set of equal valued minimum control results. The floor is selected to place a desired phase offset to the phase adjuster at the edge of minimum floor. To ensure that the correct phase adjuster offset is selected from the set of equal valued minimum control results, a control direction based penalty is added. By including both the floor and penalty, the phase adjuster steady state offset will be controlled to the edge of the minimum floor.

摘要： A method of processing an input signal to produce a corrected output signal includes generating a pre-distorted signal by distorting a digital input signal, the distortion based upon characteristics of a main amplifier, and correcting an output signal of the main amplifier to produce the corrected output signal. The output signal of the main amplifier is generated by amplifying the pre-distorted signal with the main amplifier. The correcting is based on a comparison of a signal indicative of the main amplifier output signal and a signal indicative of the digital input signal.
