Abstract. It is shown that with arbitrary sampling of discrete values of signal (for example, with the use of randomnumber generator in computer modeling), inverse transformations under Goldman formulas are generally incorrect, that is, inverse transformation does not give exact values of the initial signal. New formulas presented here give a correct result.
