METHOD FOR REDUCTION OF DIGITAL SIGNAL DISCRETE HARMONIC COMPONENTS TO CYCLIC CONVOLUTIONS

摘要

A method for reduction of digital signal discrete harmonic components to cyclic convolutions relates to the branch of computer engineering and can be used in frequency response analyzer and in digital information processing systems to calculate effectively digital signal harmonic component coefficients. The method is performed with the help of one-to-one reduction of basic matrix argument elements to cyclic matrix elements through repositioning where sequence of discrete values are provided through an entry to a determinant and analyzer array amount, after that to a line number determinant and line shaper, further cyclic substitution schedule between natural sequence and sequence of derived values of the corresponding line is formed in the generative array determinant to be supplied to the output. Applied method of digital signal discrete harmonic component reduction into cyclic convolutions allows simplifying digital signal processing method and reducing computational cost.
