RF yuqori to'xtatuvchini rad etish kichik o'lchamli telekom past o'tish filtrlari
Past chastotali filtr - yuqori chastotali signallarni olib tashlash orqali past chastotali signallarni saqlaydigan signalni qayta ishlash filtri. U chastotasi ma'lum chegaradan past bo'lgan signallarni o'tkazishga imkon beradi, lekin bu chegaradan yuqori chastotali signallarni rad etadi.
Xususiyatlari:
1. Faqat ma'lum bir chastotadan pastroq signallar o'tishi mumkin, bu chastotadan yuqori signallar filtrlanadi yoki zaiflashadi.
2. Past chastotali signallar orqali o'tayotganda, fazada deyarli hech qanday o'zgarish bo'lmaydi.
3. Odatda, past chastotali filtrlarni qurish uchun bir yoki bir nechta kondansatör va induktorlardan foydalaniladi.
Ilova:
1. silliq signal
Past-pasli filtr asosan signalni tekislash uchun ishlatiladi, u yuqori chastotali signaldagi shovqinni olib tashlashi mumkin, shunda signal yanada barqaror bo'ladi. Yumshoq signal zarur bo'lgan hollarda, past chastotali filtr yuqori chastotali shovqin shovqinini olib tashlashi mumkin, bu esa tizimni yanada ishonchli va barqaror qiladi.
2.shovqinni kamaytirish
past chastotali filtr past chastotali signalga ta'sir qilmaydi, past chastotali signalni saqlab, yuqori chastotali shovqinni filtrlash mumkin. Ovozni qayta ishlash yoki tasvirni qayta ishlashda past chastotali filtrlar shovqinni filtrlashi va qayta ishlangan signalni aniqroq qilishi mumkin.
3. xatolikni kamaytirish
past chastotali filtr xatoni kamaytirishi mumkin, ayniqsa nozik asboblarni o'lchash uchun mos keladi. Ba'zi talabchan o'lchovlarda past chastotali filtr shovqin, shovqin va boshqa omillarni olib tashlashi mumkin, shuning uchun o'lchov natijalari aniqroq va ishonchli bo'ladi.
4. keng qamrovli dastur
Past o'tish filtri deyarli hamma joyda audiodan tasvirgacha, aloqadan boshqarishgacha bo'lgan juda keng ilovalarga ega. Masalan, asosiy tarmoqli signalni qayta ishlashda past chastotali filtr kerak.
Aloqada past chastotali filtr aloqa sifatini ta'minlash uchun yuqori chastotali shovqin, shovqin va hokazolarni filtrlashi mumkin; Nazorat sohasida past chastotali filtr signalni yumshatish va shovqinni filtrlash uchun ishlatilishi mumkin.
QualwaveDC-50GHz chastota diapazonida yuqori to'xtash diapazoni rad etuvchi past o'tish filtrlarini ta'minlaydi. Past o'tish filtrlari ko'plab ilovalarda keng qo'llaniladi.
