The author once derived the probability distribution of pulse duration and that of time interval between the occurrence times of pulses in the noise process which resuls from a random series of rectangular pulses of equal amplitude and duration, their arrivals conforming to the exponential distribution. The distribution of duration and that of time interval between pulses were measured at 50 KHz with a receiver of I KHz 3-db-bandwidth using a vertical antenna at Toyokawa, 1959 and 1960. In this paper, the theoretical and experimental probability distributions are compared for duration and interval. The agreements found between them are well for the case of duration, except when the percentage the durations exceed a given length of time is very low. In the case of interval, the agreements are found to be poor for both intermediate and high thresholds. For very low threshold, the experimental distribution approximate the exponential distribution, conforming to an analytical result. The unusual increase in probability density have been observed on interval distribution at very high thresholds.
