The dither current waveform can be regulated to maintain the desired amplitude regardless of the inductance of

the coil. The dither amplitude decreases toward zero as the duty cycle nears 0 or 100%, but is constant over

the rest of the current range. The valve will not be used at zero or full current in many systems and the dither

amplitude will be constant over the usable range of coil current. The dither generator allows the dither

amplitude and frequency to be adjusted independently for maximum positive effect with minimum system

problems.
