The noise in the construction of an important factor. It can interfere with the transmission of information through communication channels, especially if the signals of low power and information to be transmitted over a long distance. Thus, the noise would be a great hindrance in the field of automation facilities, where no transmission of information on large and small distance not oboytis.Analiticheskoe study durations of noise emissions rather difficult. Rice was an approximate distribution of the duration of the intervals between the moments of crossing the zero level noise. Later, it has been proposed as solutions to approximate sufficiently high urovney.Pervye experimental data on the distribution of time intervals between zeros in normal noise were obtained by Campbell [1] .Nedavno published his research Bletekier [2], we obtain the distribution of noise emission duration, passed through a filter with a band transmittance 440 -10 250 MCPA levels from 0 to 1.69 .In this article made a complete study and results are provided.
