    Ang Band Pass Filter usa ka sirkito nga nagtugot lamang sa usa ka piho nga range sa mga frequency nga moagi, kasagaran naglangkob sa usa ka high-pass filter ug usa ka low-pass filter cascade.

    Sa usa ka bandpass filter, ang bandwidth gitino pinaagi sa duha ka cutoff frequency, mao nga ang mga signal sa ibabaw ug sa ubos sa bandpass range kinahanglang masala nga dungan. Una, ang input signal moagi sa high-pass filter aron masala ang signal ubos sa bandpass range; Dayon, ang signal sa ibabaw sa bandpass range gisala pinaagi sa low-pass filter. Ang katapusan nga output nagdala sa usa ka signal sa komunikasyon, nga mao, usa ka signal tali sa duha ka cut-off frequency. Busa, ang bandpass filter gitawag usab nga high-low pass filter.

    Ang mosunod mao ang nag-unang mga kinaiya niini:

    1. Ang mga signal sa frequency lamang sa sulod sa usa ka piho nga range ang gitugotan nga moagi, samtang nagsala o nagpaluya sa ubang mga signal sa frequency.
    2. Kung moagi sa mga signal sulod sa frequency band, mas taas nga ganansya ang makab-ot.
    3. Kasagaran, usa o daghan pa nga mga capacitor, inductors, resistors, ug uban pang mga sangkap ang gigamit sa paghimo og bandpass filter.

    Ang aplikasyon sa Band Pass Filte:

    1. Komunikasyon sa radyo: Sa komunikasyon sa radyo, ang mga filter sa bandpass mahimong magamit aron limitahan ang bandwidth sa signal, malikayan ang pagkabalda sa signal ug polusyon sa spectrum.
    2. Pagproseso sa signal: Sa pagproseso sa signal, ang mga filter sa bandpass mahimong magamit sa pagsala sa dili gusto nga mga signal sa frequency, pagpabilin lamang sa mga signal sulod sa gitinguha nga frequency band.
    3. Pagproseso sa audio: Ang mga filter sa Bandpass kaylap nga gigamit sa pagproseso sa audio aron mapahuyang ang dili gusto nga kasaba ug mga signal sa interference, sa ingon nagpauswag sa kalidad sa audio.
    4. Pagproseso sa signal sa biomedical: Sa pagproseso sa signal sa biomedical, ang mga filter sa bandpass mahimong magamit aron makuha ang mga signal sa frequency nga interes ug masala ang kasaba o uban pang mga makabalda nga signal.

    Qualwavenaghatag ug taas nga stopband rejection band pass filters sa lapad kaayo nga frequency range hangtod sa 62GHz. Ang band pass filter kay kaylap nga gigamit sa daghang mga aplikasyon.
