The relations between the statistical parameters of noise, i.e., the measured field strength of integrated atmospherics, the estimated average voltage and a series of noise parameters in the amplitude probability distribution have been obtained. The mean of the measured amplitude probability distributions is deduced with regard to the measured field strength of integrated atmospherics or the estimated average voltage, and in particular, for the latter parameter, is deduced an expression for the mean amplitude probability distribution. The impulsiveness of the noise is investigated with reference to the impulsive excursion of the trace of pen caused by the pulses of large peak appearing interruptedly. The contribution of the parts of noise envelope which exceeded over the threshold of very high voltage is investigated with regard to the average voltage or the mean square voltage of the noise envelope.}, pages = {12--24}, title = {空電雑音の統計的測定結果について(続報)}, volume = {9}, year = {1959} }
