APPROACHES TO SYNTHESIS OF HIGH-FREQUENCY FILTERS OF FINITE IMPULSE RESPONSE TYPE BASED ON CONVOLUTION ALGORITHM

Digital filters are widely used in audio and video processing, telecommunications, and other data processing industries. They enable the removal of unwanted components from signals, improve signal quality, and solve various signal processing tasks. This article covers the basic principles of digital filtering, including the stages from design to implementation of a digital filter. The text provides a comprehensive overview of the filtering process, covering parameterization and analysis of real data at the filter output.

STUDY OF THE DIELECTRIC CHARACTERISTICS OF INDUSTRIAL WOOD

In the article, we consider the model of pulse signal distortion in the computer sound card channel. The use of such a model allows expanding the possibilities of using computers in the researches of the wood properties in the form of various dielectric characteristics analysis, in particular using the computer sound card channel. This makes it possible to verify the state of the signal propagation channel during the experiment. This experiment researches samples of wood for the presence of defects. Also is proposed an approach to constructing the distortion model.
