A Sub-Channel method for the time-intervals histogram calculation

One of the methods used for presenting the results of the time-interval measurement is a two-sample-difference of quantized data histogram calculation method. The proposed Sub-Channel method allows to increase the precision and minimizes the influence of nonlinearity and quantization error during the time-interval histogram calculation. It is possible to achieve, thanks to the information obtained by an optical method, from the matrix of the probabilities of counts in particular delay cells. Using this matrix, the appropriate envelope functions and their parameters is possible for obtainable. This information is useful in the preparation of the time-intervals histogram with any resolution, independent of the real time-interval-module resolution. This paper describes a methodology of creation an envelope function and explains the process of applying a Sub-Channel method for the time-intervals histogram calculation.
