The modern level of development of digital devices of the analysis and synthesis of speech based on a method of a linear prediction, is characterized by the large variety of ways of allocation, approximation and digital representation of coded parameters. The practice of speech coding shows, that more than 70 % of information resources selected on coding of the current speech frame, is used for the description of an excitation signal of the synthesizing digital filter. The definition of laws and tendencies of development of the specified procedures will facilitate to the developers of perspective speech codecs the search of the algorithms ensuring increase of an optimality of analog-digital transformation of a speech signal in relation to elected criterion functions. In offered paper are considered the tendencies and features of an excitation signal modeling in digital devices of the speech analysis and synthesis.
