Abstract
A frequency-stabilized oscillator is frequency modulated by band-limited random varying signals used to drive a suitable transducer randomly to and artificially perturb fluid jets in an electrostatic fluid jet applicator. Such random artificial pertubation is desirable (especially with longer cross-machine orifice plates) so as to obscure printing irregularities caused by standing wave or other phenomena. However, such random variations are best made with respect to a highly stabilized center frequency.
