Due to the non-stationary conditions involved during a period of thunderstorm activity it is often difficult to make a satisfactory performance evaluation of radio systems that may be affected by atmospheric radio noise. A digital atmospheric radio noise simulator has been developed that can be programed to simulate a variety of amplitude-probability distributions and time probability distributions that are representative of atmospheric radio noise. Since the simulator has known statistics that are stationary it is useful in determining the performance of radio systems which may have to operate under the influence of random impulsive types of noise which is characteristic of atmospheric noise. The primary purpose of this memorandum is to give the details of the circuitry involved in the construction of the simulator. Author
