Bezverbnyy I. Tone signal digital analysis hardware and methodology

Test subject - a numerical processing of tonal and multitonal frequency- and phase-manipulated signals. Aim of thesis - a new numerical and analytical methods and algorithm of tonal analysis to design high-precision numerical real- time hardware of signal processing creation Analyses - numerical and analytical of tonal signal analysis; numerical methods; precision characteristic and bit capacity necessary store design methods for nonrecursive algorithm. Scientific novelty - this is offered to convert a shortage of filter bank amplitude-frequency characteristic covering into a helpful phenomenon to allow frequency determinftion of tonal signal with a maximum precision in the work. Scientific output - They are cultivated a row of new numerical and analytical methods and algorithm of frequency and phase analysis which allow to calculate frequency and phase spectrum of time limited tonal signals with a maximum precision. Practical output - offered methods of tonal and multitonal frequency- and phase-manipulated signals frequency and phase analysis within the limits of design theme 'digital computer system of low-frequency acoustical measuring system' when in use allow to create a fast-acting high-precision hydroacoustics system and communications. Introduction extent - obtain output are introduced in numerical signal processing subsystem (digital computer system 'Interferometer') of low-frequency automated measuring system device development. Use field - a measuring equipment designing on computer-based system
