Random pulse generators and generating systems using at least three oscillators. The output signals of at least two of the oscillators (110A, 110B) are combined to disturb the output signal of a final oscillator (110C) . For one configuration, combined output signals of at least two phase shift oscillators (110A, 110B) are used to modify the feedback signal (140C) of a final phase shift oscillator (110C), thus disturbing the output signal of th e final oscillator. For another configuration, the output signals of at least two phase shift oscillators are used to drive a subtractor whose output sign al is combined with the output signal of a final phase shift oscillator to driv e a subsequent subtractor, thus disturbing the output signal of the final oscillator.
