An Atmospheric Noise Burst Generator

Abstract

The testing of radio systems for data communication through the atmospheric burst error channel requires a laboratory source of the burst form of atmospheric radio noise. The paper describes the design, construction and testing of such an instrument. This noise burst generator employs hybrid circuits and, through circuitry, realizes, for the artificial noise bursts, all the observed statistical amplitude and time characteristics of the natural noise bursts in the burst form of the noise in the frequency range 0·1–10 MHz.
