Bandni rad etish filtri signalni qayta ishlashda ma'lum bir chastota diapazonidagi signalning kattaligini bostirish va boshqa chastota diapazonlaridagi signallarning o'tishiga ruxsat berish uchun ishlatiladigan filtrdir. Tarmoqli rad etish filtrining ishlash printsipi chastota domenidagi kirish signalini tahlil qilish va belgilangan chastotada shovqinni kamaytirishga erishish uchun belgilangan chastota diapazoniga muvofiq signalning amplitudasini tanlab bostirishdir.
1.Ma'lum bir chastota diapazonida signal uzatishni bloklash: tarmoqli to'xtash filtri nolga teng uzatish funktsiyasiga ega emas, lekin markaziy kesish chastotasida minimal uzatish funktsiyasiga ega. Shuning uchun u markaziy chastota diapazoni orqali signallarni uzatishni bloklashi mumkin.
2.Boshqa chastota signallarining o'tishiga ruxsat bering: Markaziy chastota diapazoniga qo'shimcha ravishda, tarmoqli to'xtash filtri boshqa barcha chastotalarning signallarini o'tkazishga imkon beradi. Bu shovqin, shovqinlarni olib tashlash va chastotaga javob berishning aniq talablariga javob berish uchun tarmoqli to'xtatuvchi filtrlardan foydalanish imkonini beradi.
3.Kichik to'lqin buzilishi: boshqa turdagi filtrlar bilan solishtirganda, tarmoqli to'xtash filtrlari kichikroq to'lqin buzilishiga ega. Bu filtrdan o'tadigan signalning shakli va amplitudasini yaxshiroq saqlashi mumkinligini anglatadi.
4.Keng polosali signalni qayta ishlash: tarmoqli to'xtash filtri keng polosali signallarni qayta ishlash uchun ishlatilishi mumkin, chunki u chastota komponentlarining ko'p qismini saqlab qolishi va faqat ma'lum bir chastota diapazonini blokirovka qilishi mumkin.
5. Fazali javob: tarmoqli to'xtash filtrining fazaviy javobi uning dizayni va amalga oshirilishiga bog'liq, lekin odatda past chastotali filtr va yuqori o'tkazuvchan filtr o'rtasida bo'ladi.
1. Elektr signalini qayta ishlash: tarmoqli to'xtash filtrlari elektr signalini qayta ishlashda ma'lum shovqin chastotalarini filtrlash uchun ishlatilishi mumkin va shu bilan signal sifatini yaxshilaydi.
2. Radioaloqa: Radioaloqada tarmoqli to'xtash filtrlari signallardagi keraksiz chastotalarni filtrlash uchun ishlatilishi mumkin va shu bilan aloqa sifatini yaxshilaydi.
3. Yuqori chastotali elektronika: tarmoqli to'xtash filtrlari kontaktlarning zanglashiga olib keladigan ishlashiga erishish uchun kontaktlarning zanglashiga olib keladigan chastota javobini sozlash uchun ishlatilishi mumkin.
4. Tibbiy asbob-uskunalar: tarmoqli to'xtatuvchi filtrlar mushaklar va boshqa tashqi shovqin manbalaridan chastotalarni filtrlash uchun elektrokardiogramma asboblari kabi tibbiy asbob-uskunalarda ishlatilishi mumkin.
QualwaveDC-18GHz chastota diapazonida yuqori to'xtash diapazoni rad etish diapazoni rad etish filtrlarini ta'minlaydi. Tarmoqli rad etish filtrlari ko'plab ilovalarda keng qo'llaniladi.
