Abstract
A step transition time reduction technique for a YIG oscillator having a capacitive filter uses an inverse transfer function to produce a predistorted drive step signal from an input drive step signal, the predistorted drive step signal being used to drive the YIG oscillator. The inverse transfer function uses R,L,C values from the oscillator circuit to generate an intermediate step in the input drive step signal, the value of the step being determined by a factor k=1/(1+e.sup.-a*pi/b) and the duration of the step being determined by a delay time dt=pi/b, where a=R/(2L) and b=(1/(LC)-R.sup.2 /(4L.sup.2)).sup.1/2.
