A magnetic field gradient system includes a magnetic field gradient coil
(20) and a magnetic field gradient amplifier (30) that operatively
communicates with the magnetic field gradient coil (20). A pre-emphasis
digital circuit (36) receives a digital magnetic field gradient control
signal and outputs pre-emphasis correction terms. The preemphasis digital
circuit includes a delay circuit (92) that delays the digital magnetic
field gradient control signal by a selected time interval to produce a
delayed digital magnetic field gradient control signal. A plurality of
digital filters (110) each have selected time constant and amplitude
parameters. The digital filters (110) receive the delayed digital
magnetic field gradient control signal and output the pre-emphasis
correction terms. A parameters memory (114) stores at least the time
constant and amplitude parameters of the digital filters (110).
