RF High Stopband ret etmek Kiçi göwrümli telekom pes passiw süzgüçler
Pes geçiş süzgüji, ýokary ýygylykly signallary aýyrmak bilen pes ýygylykly signallary saklaýan signaly gaýtadan işleýän süzgüçdir. Belli bir çäkden az ýygylykly signallara geçmäge mümkinçilik berýär, ýöne şol çäkden has ýygylykly signallary ret edýär.
Aýratynlyklary:
1. Diňe belli ýygylygyň aşagyndaky signallardan geçmäge rugsat berilýär, şol ýygylykdan ýokary signallar süzülýär ýa-da gowşaýar.
2. Pes ýygylykly signallardan geçende, fazada üýtgeşiklik ýok diýen ýaly.
3. Adatça pes geçişli süzgüçler gurmak üçin bir ýa-da birnäçe kondensator we induktor ulanylýar.
Arza:
1. ýumşak signal
pes pasly süzgüç, esasan, signaly tekizlemek üçin ulanylýar, signal has durnukly bolar ýaly ýokary ýygylykly signaldaky sesleri aýyryp biler. Smoothumşak signal gerek bolan ýagdaýynda pes geçişli süzgüç ýokary ýygylykdaky päsgelçilik sesini aýyryp biler we şeýlelik bilen ulgamy has ygtybarly we durnukly edip biler.
2. sesiň peselmegi
pes geçişli süzgüç pes ýygylykly signala täsir etmez, pes ýygylykly signaly saklamak bilen ýokary ýygylykly ses süzülip bilner. Ses gaýtadan işlemekde ýa-da şekili gaýtadan işlemekde pes pasly süzgüçler sesleri süzüp we gaýtadan işlenen signaly has düşnükli edip biler.
3. ýalňyşlygy azaltmak
pes passiw süzgüç ýalňyşlygy azaldyp biler, esasanam gurallary takyk ölçemek üçin amatly. Käbir talap edilýän ölçeglerde pes geçişli süzgüç, sesiň, päsgelçiligi we beýleki faktorlary aýyryp biler, şeýlelik bilen ölçeg netijeleri has takyk we ygtybarly bolar.
4. ýüz tutmagyň giň gerimi
Pes geçiş süzgüçinde sesden şekile, aragatnaşykdan dolandyryşa çenli hemme ýerde diýen ýaly köp sanly programma bar. Mysal üçin, baseband signalyny gaýtadan işlemekde pes pasly süzgüç zerurdyr.
Aragatnaşykda, pes geçişli süzgüç, ýokary hilli ses, päsgelçilik we ş.m. süzüp, aragatnaşygyň hilini üpjün edip biler; Dolandyryş pudagynda pes pasly süzgüç signaly ýumşatmak we ses süzmek üçin ulanylyp bilner.
QualwaveDC-50GHz ýygylyk diapazonynda ýokary zolakly ret etmek pes passiw süzgüçleri üpjün edýär. Pes geçiş süzgüçleri köp programmalarda giňden ulanylýar.
