Some Results on Zero Crossing Distribution of Non-stationary Random Noise

Abstract

Non-stationary random noise processes are frequently observed in many problems of communication and control, which have not been given proper importance because of insufficiency in equipments and mathematical complications. In the present paper, therefore, an experimental investigation has been made to study the distribution of zero crossing interval of non-stationary random noise, obtained from an electronic communication system. An analytical explanation has also been developed by taking the ‘box’ theory of ensemble averaging of power spectral density and applying it to McFadden's relation for zero crossing interval which is quite flexible in its assumption for high degree of sampling. It has been observed that the predicted results agree with the observed values to a large extent.
