Calculation of a "narrowed" autocorrelation function.
نویسندگان
چکیده
A method of calculating an autocorrelation function with extremely narrow peaks is described. This is done by including terms in the autocorrelation expression corresponding to delays at 2 tau, 3 tau, etc., in addition to the usual term with delay tau. Implications in the frequency domain are explored. Graphs of this autocorrelation function for a number of violin sound samples, including a two-octave scale, vibrato, and glissando, are presented. Graphs of the autocorrelation function for some synthetic sound samples are also included.

متن کاملAnalysis of Decision Diagram based Methods for the Calculation of the Dyadic Autocorrelation
This paper discusses in a tutorial way, methods for calculation of the logic autocorrelation of switching functions. We compare calculation over function vectors and decision diagrams and perform an experimental analysis of performances of these methods with an emphasis on their time complexity.
متن کاملRemarks on Calculation of Autocorrelation on Finite Dyadic Groups by Local Transformations of Decision Diagrams
The paper considers calculation of autocorrelation functions on finite dyadic groups over decision diagrams. The methods exploit recursive structure of both autocorrelation matrices and decision diagrams. First, it is discussed calculation of the autocorrelation through the Wiener-Khinchin theorem implemented over decision diagrams. Then, it is proposed a method for calculation of separate auto...
متن کاملMeasurement of Plain Weave Fabrics Density Using Fourier Transforms
Warp and weft spacing and its coefficient of variation affect the physical properties of fabrics such as fabric hand, frictional and mechanical properties. In this paper the weft and warp spacing and its coefficient of variation for plain weave is calculated using Fourier transforms. Different methods have been used in this work including autocorrelation function. First, two dimensional power s...
