Description: The questions of synthesis of signals with a compact spectrum fitting to criterion Nyquist on the basis of splines-functions are considered. By criterion of a minimum of power in side lobes the synthesis of signals as splines-functions second, third and fourth order is fulfilled. The obtained signals have a prize by the pointed criterion, in comparison with a signal having spectrum of a type «raised cosine».
