Abstract:
1. A precision, multivibrator, said multivibrator comprising: timing means for providing a signal that is responsive to time constant; means for providing a reference signal; comparator means having one or more inverting and noninverting input pairs; switch means responsive to comparator means; said switch means for alternately reversing signal connections to said inverting and said non-inverting comparator means inputs by either connecting said timing means signal to said non-inverting input and said reference means signal to said inverting input or connecting said reference means signal to said non-inverting input and said timing means signal to said inverting input; and said comparator means responsive to said timing means signal and reference means signal, whereby average timing of the multivibrator output is a stable function of the difference between said timing means signal and said reference means signal.
