Цифровая обработка сигналов

Abstract

Рассмотрены теоретические основы разложения функций в ряды, описания Ð±Ð°Ð·Ð¾Ð²Ñ‹Ñ Ð°Ð»Ð³Ð¾Ñ€Ð¸Ñ‚Ð¼Ð¾Ð² и программ цифровой обработки: быстрого преобразования Фурье, разложения сигналов в действительный и комплексный ряд Фурье, цифровой фильтрации, корреляции, линейной свёртки. Описаны приёмы решения ÑÐ»Ð¾Ð¶Ð½Ñ‹Ñ Ð·Ð°Ð´Ð°Ñ‡ путём комбинации Ð½ÐµÑÐºÐ¾Ð»ÑŒÐºÐ¸Ñ Ð±Ð°Ð·Ð¾Ð²Ñ‹Ñ Ð°Ð»Ð³Ð¾Ñ€Ð¸Ñ‚Ð¼Ð¾Ð² цифровой обработки сигналов. Рассмотрены основы анализа Ð½ÐµÑÑ‚Ð°Ñ†Ð¸Ð¾Ð½Ð°Ñ€Ð½Ñ‹Ñ ÑÐ¸Ð³Ð½Ð°Ð»Ð¾Ð² и очистки сигналов от шумов на базе декомпозиции Хуанга и преобразования Гильберта. Предназначено для студентов Ð²Ñ‹ÑÑˆÐ¸Ñ Ñ‚ÐµÑ Ð½Ð¸Ñ‡ÐµÑÐºÐ¸Ñ ÑƒÑ‡ÐµÐ±Ð½Ñ‹Ñ Ð·Ð°Ð²ÐµÐ´ÐµÐ½Ð¸Ð¹, Ð¾Ð±ÑƒÑ‡Ð°ÑŽÑ‰Ð¸Ñ ÑÑ по направлению подготовки 09.03.01 - «Информатика и вычислительная Ñ‚ÐµÑ Ð½Ð¸ÐºÐ°Â», 09.03.04 - «Программная инженерия», студентам Ð´Ñ€ÑƒÐ³Ð¸Ñ ÑÐ¿ÐµÑ†Ð¸Ð°Ð»ÑŒÐ½Ð¾ÑÑ‚ÐµÐ¹, Ð¸Ð·ÑƒÑ‡Ð°ÑŽÑ‰Ð¸Ñ Ð´Ð¸ÑÑ†Ð¸Ð¿Ð»Ð¸Ð½Ñƒ «Цифровая обработка сигналов».
