Abstract
This reply comments on the results and conclusions of the above paper. The authors analyze the proposed numerical method (the trapezoidal rule) for numerical integration as well as the possible sources of error in this type of processing, and derive analytical expression for them. In addition, the authors provide comments on the principle of signal reconstruction proposed in the above paper and show that the postprocessing operation is not necessary. It has been presented that no doubts exist in the experimental results given in the commented papers, with an accuracy of 0.01%
