Abstract
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. It is an important resource for technicians, engineers,
students, and anyone interested in signal processing.
