Xususiyatlari:
- Yuqori to'xtash chizig'ini rad etish
- Kichik o'lcham
U chastotasi ma'lum chegaradan yuqori bo'lgan signallarni o'tkazishga imkon beradi, lekin bu chegaradan past chastotali signallarni rad etadi. Passiv yuqori o'tkazuvchan filtr passiv komponentlardan (R, L va C) tashkil topgan filtr bo'lib, chastota o'zgarishi bilan kondansatör va induktorlarning reaktivligi o'zgarishi printsipidan foydalanadi. Yuqori o'tkazuvchan filtrning afzalliklari quyidagilardan iborat: sxema nisbatan sodda, doimiy tok manbaini talab qilmaydi, yuqori ishonchlilik; U past chastotali signalni samarali ravishda bostirishi va yuqori chastotali signalni o'tkazishi mumkin. Yuqori o'tkazuvchan filtrning kamchiliklari shundaki, zaiflashuv tezligi nisbatan katta bo'lib, bu signalning aniqligiga ta'sir qilishi mumkin; O'tish diapazonidagi signal energiya yo'qotilishiga ega, yuk ta'siri aniq va induktorlardan foydalanish elektromagnit induktsiyani keltirib chiqarishi oson va filtrning hajmi va og'irligi L indüktansı katta bo'lganda nisbatan katta bo'ladi, bu esa qo'llanilmaydi. past chastotali domen.
1. Ovozni qayta ishlash: Yuqori chastotali filtrlar past chastotali shovqinni yoki boshqa keraksiz past chastotali signallarni zaiflashtirish va shu bilan audio sifatini yaxshilash uchun audio ishlov berishda ishlatilishi mumkin.
2. Tasvirga ishlov berish: Tasvirni qayta ishlashda tasvirlardagi yuqori chastotali tafsilotlarni yaxshilash, ularni aniqroq qilish uchun yuqori o'tish filtrlaridan foydalanish mumkin.
3. Sensor signalini qayta ishlash: Yuqori o'tish filtrlari sensor signallarida past chastotali shovqinni filtrlash uchun ishlatilishi mumkin, bu esa signal ishonchliligi va aniqligini oshiradi.
4. Radioaloqa: Radioaloqada yuqori o'tish filtrlari past chastotali shovqin va shovqin signallarini filtrlash uchun ishlatilishi mumkin va shu bilan aloqa sifatini yaxshilaydi.
Qualwave60 gigagertsgacha bo'lgan chastota diapazonida yuqori to'xtash diapazoni rad etuvchi yuqori o'tish filtrlarini taqdim etadi. Yuqori o'tish filtrlari ko'plab ilovalarda keng qo'llaniladi.
