We demonstrate a controlled phase change of p in a degenerate superposition by altering a laser frequency by only 10 MHz. The method relies on the preparation of an adiabatic state involving the M = Β±2 and M = 0 states of the 3 P 2 (J = 2) level of metastable neon. Dependent on the frequency, the pr
## Abstract Stability analysis and design of an automatic frequency control (AFC) system for in vivo continuousβwave EPR spectroscopy is described. The openβloop function of the feedback control system for the AFC was derived and the stability of the feedback loop systematically examined. A stabili
Digital repetitive control is a technique which allows to track periodic references and/or reject periodic disturbances. Repetitive controllers are usually designed assuming a fixed frequency for the signals to be tracked/rejected, its main drawback being a dramatic performance decay when this frequ
