Synthesis of a mathematical structural-functional model of a digital all-pass filter

Abstract

The research is devoted to the synthesis of a mathematical structural and functional model of a digital all-pass filter. The synthesized model provides a formalized description of a all-pass filer structure and its operation, and forms the basis for further analysis and software implementation in embedded digital signal processing systems. The digital all-pass filter, implemented in software on a microcontroller, can be used as a separate element in the signal path for correcting phase distortion and group delay that occur during signal transmission.
