Raqamli filtrlash usullarining signal sifatiga ta’siri
Abstract
Ushbu maqolada raqamli filtrlash usullarining signal sifatiga ta’siri o‘rganilgan. Signal tarkibidagi shovqinlarni kamaytirish hamda foydali axborotni ajratib olishda FIR va IIR filtrlardan foydalanish imkoniyatlari tahlil qilindi. Turli filtr parametrlarining chiqish signaliga ta’siri modellashtirish asosida baholandi. Tadqiqot natijalari shuni ko‘rsatdiki, to‘g‘ri tanlangan filtr signal aniqligi va uzatish sifatini sezilarli yaxshilaydi. Shuningdek, real vaqt tizimlarida filtrlash algoritmlarining samaradorligi ko‘rib chiqilgan. Olingan xulosalar telekommunikatsiya va avtomatika tizimlarida qo‘llash uchun muhim ahamiyatga ega. Signal qayta ishlashda samarali yechimlar beradi va amalda foydalidir.
