A new method is suggested for reconstruction of signals of unknown shape by their bispectral density. The new approach is based on application of smooth functions such as cosine and sine — instead of the discontinuous function of the “arctangent of bispectrum argument” type, traditionally accepted in phase measurements. The use of simulation permits to assess effectiveness of the suggested method of reconstruction of signals with the first genus discontinuities at different discretization intervals.
