Random pulse generators and generating systems using at least three oscillators. The output signals of at least two of the oscillators are combined to disturb the output signal of a final oscillator. For one configuration, combined output signals of at least two phase shift oscillators are used to modify the feedback signal of a final phase shift oscillator, thus disturbing the output signal of the final oscillator. For another configuration, the output signals of at least two phase shift oscillators are used to drive a subtractor whose output signal is combined with the output signal of a final phase shift oscillator to drive a subsequent subtractor, thus disturbing the output signal of the final oscillator.
