Ushbu maqolada signal tizimlarida yuzaga keladigan shovqinlarni kamaytirish va signal-shovqin nisbatini (SNR) yaxshilash usullari tahlil qilingan. Tadqiqot davomida klassik raqamli filtrlar, veyvlet o‘zgartirishlari va zamonaviy adaptiv filtrlash algoritmlarining samaradorligi o‘zaro solishtirilgan. Shuningdek, nutq signallarini tozalashda spektral ayirish usulining afzalliklari va cheklovlari ko‘rib chiqilgan. Olingan natijalar shuni ko‘rsatadiki, gibrid usullarni qo‘llash dinamik shovqinli muhitda signal sifatini sezilarli darajada oshiradi. Maqola radioaloqa, tibbiy diagnostika va audio muhandislik sohasida ishlovchi mutaxassislar uchun mo‘ljallangan.
