Band stop filter

Ang mga filter ng Band-Stop ay may kakayahang hadlangan o maipakita ang mga signal sa isang tiyak na saklaw ng dalas, habang ang mga senyas sa labas ng saklaw na iyon ay mananatiling malinaw.

Ang mga filter ng band-stop ay may dalawang frequency ng cutoff, isang mababang dalas ng cutoff at isang mataas na dalas ng cutoff, na bumubuo ng isang saklaw ng dalas na tinatawag na "passband". Ang mga senyas sa saklaw ng passband ay higit sa lahat ay hindi maapektuhan ng filter. Ang mga filter ng band-stop ay bumubuo ng isa o higit pang mga saklaw ng dalas na tinatawag na "stopbands" sa labas ng saklaw ng passband. Ang signal sa stopband range ay na -attenuated o ganap na naharang ng filter.

Pangkalahatang -ideya

Ang Stopband bandwidth ay tumutukoy sa lapad ng stopband range, iyon ay, ang dalas ng dalas sa pagitan ng mataas at mababang mga frequency ng cutoff. Ang mga filter ng Band-Stop ay may iba't ibang mga rate ng pagpapalambing, na ginagamit upang kumatawan sa antas ng pagpapalambing ng signal sa saklaw ng stopband na may kaugnayan sa signal sa saklaw ng passband. Ang ilang mga filter ng band-stop ay maaaring magkaroon ng mga ripples sa saklaw ng passband, iyon ay, mga pagbabago sa pakinabang ng signal sa isang tiyak na saklaw ng dalas. Ang mga Ripples ay maaaring kontrolado sa pamamagitan ng disenyo ng filter at pag -optimize upang matiyak ang kalidad ng signal sa saklaw ng passband. Ang mga filter ng band na hihinto ay karaniwang may tiyak na mga impedance ng input at output upang tumugma sa mga kinakailangan ng impedance ng mapagkukunan ng signal at pag-load.

Ang mga filter ng band-stop ay malawakang ginagamit sa iba't ibang larangan, tulad ng mga sistema ng komunikasyon, kagamitan sa audio, amplifier, receiver ng radyo, atbp.
