Umumiy ma'lumot
Past chastotali filtrlar turli xil susayish tezligiga ega bo'lishi mumkin, bu yuqori chastotali signalning kesish chastotasidan past chastotali signalga nisbatan susayish darajasini ifodalaydi. Susayish tezligi odatda desibellarda (dB) ifodalanadi, masalan, 20dB/oktava har bir chastotada 20dB susayishni anglatadi.
Past chastotali filtrlar turli xil turlarda, masalan, ulanadigan modullar, sirtga o'rnatish moslamalari (SMT) yoki ulagichlarda qadoqlanishi mumkin. Qadoq turi qo'llanilish talablari va o'rnatish usuliga bog'liq.
Past chastotali filtrlar signalni qayta ishlashda keng qo'llaniladi. Masalan, audioni qayta ishlashda yuqori chastotali shovqinni yo'q qilish va audio signalning past chastotali komponentlarini saqlab qolish uchun past chastotali filtrlardan foydalanish mumkin. Tasvirni qayta ishlashda past chastotali filtrlardan tasvirlarni tekislash va tasvirlardan yuqori chastotali shovqinni olib tashlash uchun foydalanish mumkin. Bundan tashqari, past chastotali filtrlar ko'pincha simsiz aloqa tizimlarida yuqori chastotali shovqinlarni bostirish va signal sifatini yaxshilash uchun ishlatiladi.
