RFTYT Bandstop Filter Q Factor Frequency Range Itinatampok na Larawan

Saklaw ng Dalas ng RFTYT Bandstop Filter Q Factor

Ang mga band-stop na filter ay may kakayahang mag-block o mag-attenuate ng mga signal sa isang partikular na frequency range, habang ang mga signal sa labas ng range na iyon ay nananatiling transparent.

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

Pangkalahatang-ideya

Ang stopband bandwidth ay tumutukoy sa lapad ng hanay ng stopband, iyon ay, ang frequency span sa pagitan ng mataas at mababang cutoff frequency.Ang mga filter ng band-stop ay may iba't ibang mga rate ng attenuation, na ginagamit upang kumatawan sa antas ng attenuation ng signal sa hanay ng stopband na nauugnay sa signal sa hanay ng passband.Ang ilang mga band-stop na filter ay maaaring may mga ripples sa hanay ng passband, iyon ay, mga pagbabago sa nakuha ng signal sa isang partikular na hanay ng frequency.Maaaring kontrolin ang mga ripple sa pamamagitan ng disenyo ng filter at pag-optimize para matiyak ang kalidad ng signal sa hanay ng passband.Ang mga band-stop na filter ay karaniwang may partikular na input at output impedances upang tumugma sa mga kinakailangan sa impedance ng pinagmumulan ng signal at load.

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