Band Stop Filter

Ang mga band-stop filter ay may kakayahang harangan o pahinain ang mga signal sa isang partikular na saklaw ng frequency, habang ang mga signal sa labas ng saklaw na iyon ay nananatiling transparent.

Ang mga band-stop filter ay may dalawang cutoff frequencies, isang mababang cutoff frequency at isang mataas na cutoff frequency, na bumubuo ng isang frequency range na tinatawag na "passband". Ang mga signal sa passband range ay hindi gaanong maaapektuhan ng filter. Ang mga band-stop filter ay bumubuo ng isa o higit pang mga frequency range na tinatawag na "stopbands" sa labas ng passband range. Ang signal sa stopband range ay pinapahina o ganap na hinaharangan ng filter.

Pangkalahatang-ideya

Ang bandwidth ng stopband ay tumutukoy sa lapad ng saklaw ng stopband, ibig sabihin, ang saklaw ng dalas sa pagitan ng mataas at mababang cutoff na mga frequency. Ang mga band-stop filter ay may iba't ibang antas ng pagpapahina, na ginagamit upang kumatawan sa antas ng pagpapahina ng signal sa saklaw ng stopband kaugnay ng signal sa saklaw ng passband. Ang ilang band-stop filter ay maaaring may mga ripples sa saklaw ng passband, ibig sabihin, mga pagbabago sa gain ng signal sa isang partikular na saklaw ng frequency. Ang mga ripples ay maaaring kontrolin sa pamamagitan ng disenyo at pag-optimize ng filter upang matiyak ang kalidad ng signal sa saklaw ng passband. Ang mga band-stop filter ay karaniwang may mga partikular na input at output impedances upang tumugma sa mga kinakailangan sa impedance ng pinagmulan ng signal at load.

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