Features of the practical realization of the generating filter of the digital transmitter

摘要

Specific features of the practical realization of a digital generating filter for the transmitter with multiposition phase modulation used in the systems of mobile communications are considered in the report. Results obtained in the investigation of the effect of weight window on the spectral characteristics of the output signal are reported. As a result of analysis performed, recommendations concerning the choice of the minimal length of the digital generating filter are given.
