| Abstract: | The probability theory is used to analyse the property of middle-value filters in this paper. By applying the sequence distribution formula of stochastic variables, the property parameter formulae for general distribution are deduced, and the property parameters of exponential distribution and Gauss distribution are also obtained. The method used and the formula deduced are of great value to design and application of the filter. |
