1) Lub band txiav tawm zaus fp = wp / (2p) yog qhov zaus ntawm qhov chaw ciam teb ntawm qhov hla band thiab thaj chaw hloov pauv, thiab cov teeb liab nce ntawm qhov taw tes ntawd poob mus rau qis qis ntawm qhov chaw tsim khoom;
2) Band cutoff zaus fr = wr / (2p) yog qhov zaus ntawm qhov chaw ciam teb ntawm cov qhab thiab qhov chaw hloov pauv, thiab cov teeb liab ploj ntawm qhov taw tes poob mus rau qis qis ntawm tus txiv neej;
3) Kev hloov zaus fc = wc / (2p) yog qhov zaus ntawm lub teeb liab fais fab attenuation mus rau 1/2 (txog 3dB), ntau zaus, FC feem ntau yog siv los ntawm kev hla lossis band txiav ntau zaus;
4) Lub ntuj zaus f0 = w0 / (2p) yog tias thaum lub voj voog tsis muaj qhov poob, lub suab nrov zaus ntawm cov lim dej, cov circuits nyuaj feem ntau muaj ntau zaus.
Qhov nce ntawm cov lim dej hauv lub band tsis tas li.
1) rau qhov tsawg-pass lim los ntawm band nce KP feem ntau yog hais txog qhov nce thaum w = 0;high-pass hais txog qhov nce ntawm w→∞;nrog cov kev cai dav dav hais txog qhov nce ntawm qhov nruab nrab zaus;
2) rau band Resistance lim, lub rub siv ntawm txoj siv yuav tsum tau muab, thiab qhov kev noj qab haus huv yog txhais tau tias yog qhov hloov pauv ntawm qhov nce;
3) Cov qhab nce hloov ntim KP yog hais txog qhov kev hloov pauv siab tshaj plaws ntawm qhov nce ntawm txhua lub ntsiab lus hauv pawg, thiab yog tias KP nyob hauv db, nws hais txog qhov sib txawv ntawm qhov nce DB tus nqi.
Lub damping coefficient yog lub luag haujlwm ntawm tus cwj pwm ntawm kab pheeb ces kaum ntawm lub lim raws li lub teeb liab w0, thiab nws yog qhov ntsuas los sawv cev lub zog lwj hauv lub lim.Lub inverse ntawm damping coefficient yog hu ua qhov zoo tshaj plaws, uas yog ib qho tseem ceeb Performance index ntawm zaus xaiv yam ntxwv ntawm * Valence band pass thiab band kuj lim, q = w0 / W.
W hauv cov qauv yog 3dB bandwidth ntawm band-pass lossis band-resistance lim, W0 yog qhov nruab nrab zaus, thiab ntau zaus qhov chaw zaus yog sib npaug rau lub ntuj zaus.
Qhov rhiab heev ntawm qhov ntsuas kev ua tau zoo y ntawm lub lim mus rau X variation ntawm ib qho kev tivthaiv tsis raug kaw raws li SXY, txhais tau tias: sxy = (dy / y) / (dx / x).
Lub rhiab heev tsis yog ib lub tswv yim nrog lub rhiab heev ntawm lub ntsuas ntsuas los yog Circuit Court system, thiab qhov me me ntawm qhov rhiab heev, qhov muaj zog ntawm kev ua txhaum ntawm lub Circuit Court thiab siab dua qhov kev ruaj ntseg.
