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. The authors discuss various types of digital filters, such as infinite impulse response (IIR) and finite impulse response (FIR) filters, each with its own unique characteristics, advantages, and disadvantages. This information will assist in selecting the most appropriate filter for a given task. The article discusses the use of digital filters for signal processing tasks, including noise reduction, in various real-world scenarios. The language used is clear, concise, and objective, with a formal register and precise word choice. The article discusses the use of digital filters for signal processing tasks, including noise reduction, in various real-world scenarios. The sentences and paragraphs have a logical flow of information with causal connections between statements. The text is free from grammatical errors, spelling mistakes, and punctuation errors. It aims to help readers understand the functionality of digital filters, how to select the appropriate filter for a specific task, and how to use them to enhance signal quality. The text adheres to conventional academic structure and formatting, with consistent citation and footnote style. No changes in content have been made to the original text.
