The error of evaluation of Hadamard transform measurement for the case of being data short is analysed and a formula is deduced. It comes the conclusion that when data are not complete one can make up the absent data by rand on values within the interval between the maximum and minimum readings of the data in hand, and decoding by computer, one can get the information of the spectrum in appropriate accuracy.
