Sefa yekuteerera inotsamira kakawanda Amplifier dunhu, kushanda muodhiyo frequency renji, 0 Hz kusvika kupfuura 20 kHz.
Mazhinji marudzi emafirita aripo kune maapplication anosanganisira graphic equalizers, synthesizer, manzwiro, maCD player uye virtual reality systems.
Kuve frequency inotsamira amplifier, mune yayo yakakosha fomu, odhiyo sefa yakagadzirirwa kukwidziridza, kupfuudza kana kudzikisira (negative amplifier) mamwe ma frequency renji.
Mhando dzakajairwa dzinosanganisira yakaderera-pass mafirita, ayo anopfuura nepasi pemafafitera ari pasi peawo cutoff frequency, uye zvishoma nezvishoma anodzora mafrequency pamusoro peiyo cutoff frequency.
Iyo yepamusoro-pass sefa inoita zvakapesana, ichipfuura yakakwira frequency pamusoro peiyo cutoff frequency, uye zvishoma nezvishoma inodzora mafrequency pazasi peiyo cutoff frequency.
Bandpass sefa inopfuudza mafrequency pakati peayo maviri cutoff frequency, uku ichiremedza avo vari kunze kwerenji.
Iyo bhendi-reject sefa, inoremedza mafambiro pakati peayo maviri cutoff frequencies, ichipfuura idzo dziri kunze kwe 'ramba' renji.
Yese-pass sefa, inopfuura ese ma frequency, asi inokanganisa chikamu chechero yakapihwa sinusoidal chikamu zvinoenderana ne frequency yayo.
Mune mamwe maapplication, senge mudhizaini yegraphic equalizers kana maCD player, mafirita anogadzirwa zvinoenderana neseti yezvinangwa senge pass band, pass band attenuation, stop bhendi, uye kumisa bhendi attenuation, uko mabhendi epasi ndiwo frequency renji iyo odhiyo inodzikiswa zvishoma pane yakataurwa, uye mabhendi ekumira ndiwo ma frequency renji ayo odhiyo inofanira kudzikiswa nehushoma hwakatarwa.
Mune zvimwe zviitiko zvakaoma, iyo yekuteerera sefa inogona kupa mhinduro loop, iyo inosuma resonance (kurira) padivi pekudzikisira.
Audio mafirita anogona zvakare kugadzirwa kuti ape pfuma (boost) pamwe nekudzikisira. Mune mamwe maapplication, senge nemasynthesizer kana ruzha mhedzisiro, kunaka kwesefa kunofanirwa kuongororwa zvine musoro.
Odhiyo mafirita anogona kuitwa muanalog wedunhu seanalog mafirita kana muDSP kodhi kana komputa software sedhijitari mafirita.
Kazhinji, izwi rekuti 'audio sefa' rinogona kushandiswa kureva chero chinhu chinoshandura timbre, kana harmonic zvirimo. chiratidzo chekuteerera.
Ini ndini Joost Nusselder, muvambi weNeaera uye mushambadzi wemukati, baba, uye ndinoda kuyedza michina mitsva ine gitare pamoyo pechido changu, uye pamwe nechikwata changu, ndanga ndichigadzira zvakadzama zvinyorwa zveblog kubva 2020. kubatsira vaverengi vakavimbika nekurekodha nemagitare.
