## Abstract A programmable preemphasis system has been developed for eddyโcurrent compensation in gradient sets with or without active screening. Preemphasis parameters are nonvolatile but can be changed rapidly when working with interchangeable gradient sets. The design allows easy retrofit to exi
## Abstract We describe a modified preโemphasis network that uses a number of fixed time constants, only whose amplitudes are adjustable. In comparison with variable time constant preโemphasis networks we have used, the fixed time constant network is more effective and easier to set on the fly. We
## Abstract Starting from the timeโharmonic Maxwell equations at lowโfrequency eddy current approximation the Hโ__ฯ__ formulation is presented. An equivalent system of boundary integral equations of the second kind on the conductor surface (resp. the conductor/dielectric) is derived. Discretizing t
