摘要：
Algorithms are developed for calculating spectral power density (SPD) of signals in the modified Sobolev space W¯21. Identity of the signals SPD in the spaces W¯21 and L2 is proved. Higher accuracy of discrete signal SPD representation in the space W¯21 than in the space L2 is shown in the choice of discretization frequency less than the Kotel'nikov frequency.
