TIME DISTORTION SIGNALS ANALYSIS IN DIGITAL MAGNETIC RECORDING CHANNELS USING "CATERPILLAR" ALGORITHM.
In this article it is described the implementation method of the temporary distortions intervals of the information signal and allocation of quasi-deterministic and purely random jitter components in the read channel of digital magnetic recording (DMR). For the implementation process it was used the «Caterpillar» algorithm of singular spectral analysis. As the result of this algorithm we got the decomposition of the initial time series into simple components: slow trends and other periodic or oscillatory components and pure noise components. Research and analysis of these components is significant for the design of Electromechanical units and circuitry channels recording-playing equipment DMR. The efficiency of the proposed method is illustrated by means of modeling correction phase jitter information signal system inertial phase-locked loop.
