RF High Stopband Rejection Me Me Telecom High Pass Lim
High-pass lim yog lub teeb liab ua cov lim dej uas khaws cov teeb liab ntau zaus los ntawm kev tshem tawm cov teeb liab tsawg zaus.
Nws tso cai rau cov teeb liab nrog ntau zaus ntau dua li ib qho chaw pib kom dhau, tab sis tsis lees txais cov teeb liab nrog zaus tsawg dua qhov pib. Lub passive high-pass lim yog lub lim uas muaj cov khoom siv passive (R, L thiab C), siv lub hauv paus ntsiab lus uas cov reactance ntawm capacitors thiab inductors hloov nrog kev hloov ntawm zaus. Qhov zoo ntawm high-pass lim yog: lub Circuit Court yog qhov yooj yim, tsis tas yuav DC fais fab mov, muaj kev ntseeg siab; Nws tuaj yeem cuam tshuam cov teeb liab tsawg zaus thiab ua rau lub teeb liab siab dhau los. Qhov tsis zoo ntawm cov lim dej siab yog qhov attenuation tus nqi kuj loj, uas yuav cuam tshuam qhov tseeb ntawm lub teeb liab; Lub teeb liab nyob rau hauv lub passband muaj lub zog poob, cov nyhuv load yog pom tseeb, thiab kev siv cov inductors yog ib qho yooj yim ua rau electromagnetic induction, thiab lub ntim thiab qhov hnyav ntawm lub lim kuj loj heev thaum lub inductance L loj, uas yog tsis muaj feem xyuam rau hauv lub inductor. qhov tsawg zaus domain.
High-pass lim yog feem ntau siv hauv suab, yees duab, thiab cov duab ua los txhim kho cov teeb liab kom pom tseeb thiab txo cov suab nrov. Piv txwv li:
1. Audio processing: High pass filters can be used in audio processing to weaken low-frequency nrov nrov lossis lwm yam tsis tsim nyog cov teeb liab tsawg zaus, yog li txhim kho lub suab zoo.
2. Kev ua duab: Hauv kev ua cov duab, cov ntxaij lim dej siab dhau tuaj yeem siv los txhim kho cov ntsiab lus ntau zaus hauv cov duab, ua kom pom tseeb.
3. Sensor teeb liab ua: Cov lim dej siab dhau tuaj yeem siv los lim tawm cov suab nrov qis hauv cov teeb liab sensor, yog li txhim kho teeb liab kev ntseeg tau thiab raug.
4. Kev sib txuas lus hauv xov tooj cua: Hauv kev sib txuas lus hauv xov tooj cua, cov ntxaij lim dej siab dhau tuaj yeem siv los lim tawm cov suab nrov tsawg thiab cuam tshuam cov teeb liab, yog li txhim kho kev sib txuas lus zoo.
Qualwavekhoom siv siab stopband rejection high pass filters nyob rau hauv ntau zaus mus txog 60GHz. Cov lim dej siab dhau tau siv dav hauv ntau daim ntawv thov.
