Abstract
A noise generator system is described in which the amplitude of a noise source is stabilized by a feedback loop to an automatic gain control circuit, and wherein the output of the system is time controlled by means of a differential pair amplifier.
Claims6
A noise generator system comprising, a noise source, amplifier means including automatic gain control means responsive to an applied voltage, means for applying the output of said noise source to the input of said amplifier means, and a feed back loop coupled between the output of said amplifier means and the input of said automatic gain control means, said feed back loop including means for producing a voltage representative of the difference between the output of said amplifier means and a reference voltage.
