Mayelana nalolu hlelo lokusebenza

Ukusethwa Komsindo Wemoto kungabonwa njenge-acoustic multimeter yezilinganiso zesikhathi sangempela: Emotweni, indawo yokukhweza yezipikha noma izindawo zokulalela ezingashintshwa. Ngakho-ke izilinganiso zigxile ekuthuthukiseni impendulo yemvamisa. Uhlelo lokusebenza lunikeza amathuluzi adingekayo nge-fun generator, i-analyzer yesikhathi sangempela kanye ne-spectrogram. Ukwengeza, i-oscilloscope isiza ekuxazululeni izinkinga: Ngaphambi kokulinganisa kokuqala, isipiliyoni sibonise ukuthi kufanele kuqinisekiswe ukuthi izikhulumi kanye nama-crossovers axhunyiwe futhi alungiswa ngendlela efanele. Ngokungeziwe ezilinganisweni zesikhathi sangempela, impendulo yemvamisa kanye nokuphendula komfutho kungalinganiswa nge-logsweep ukuze kuhlaziywe okunembe kakhudlwana.


Izilinganiso zesikhathi sangempela

- Ukubuka okubili, okulungiseka ngokukhululekile nge-oscilloscope, i-function generator, i-real-time analyzer kanye ne-spectrogram
- Imibhobho ye-Mono neyestereo iyasekelwa
- Ukusetshenziswa kwemibhobho yokulinganisa (ukungenisa kwejika lokulinganisa)
- IsiNgisi nesiJalimane

I-Oscilloscope
- I-Trigger ne-rolling display
- Iziteshi ezi-4: Imakrofoni (L, R), ijeneretha yokusebenza (L, R)
- Ukulawulwa kokuthola okuzenzakalelayo okushintshwayo kwesiteshi semakrofoni (AGC)

Ijeneretha yomsebenzi
- Amajeneretha amabili alungisekayo ngokwehlukana, okukhiphayo okuxutshwayo
- Umsindo wesine nomhlophe
- Ukuqhuma
- I-polarity, ibhalansi kanye nokubambezeleka kwamashaneli e-stereo alungiseka

I-Realtime Analyzer ne-Spectrogram
- Iwindi le-FFT, ubude, isilinganiso kanye nokugqagqana kwama-FFT alandelanayo
- Sondeza ngokuthinta kweminwe emi-2
- Inkinobho yokumisa isikhashana nezifinyezo zamajika amaningi ukuze kuhlaziywe imicimbi emifushane yomsindo


Ukulinganisa nge-logsweep

- Umsebenzi wochungechunge wokulinganisa okusheshayo ezindaweni eziningi zemakrofoni
- Ukuzimisela okuzenzakalelayo kokuma kwemakrofoni okusekelwe ezikhathini zohambo lomsindo
- Ukufiphala kokubonisa okubaliwe (isihlungi sekamu) ukuze siqhathaniswe nedatha yokulinganisa
- Ukusabela okuguquguqukayo - okuqondile: idatha eluhlaza, idatha ebushelelezi, impendulo yesinyathelo, ijika lesikhathi samandla
- Impulse response - logarithmic: idatha eluhlaza, idatha ebushelelezi, amanani aphezulu, ijika lesikhathi samandla
- Ukuboniswa kwempendulo yemvamisa kanye nempendulo ye-impulse eyenziwe ngokwezifiso: ukusondeza, amajika angagudluzwa ngokumelene nomunye, ama-oda ahlukene...
- Ukuthunyelwa kwemiphumela: ngefomethi ye-HTML
- Ukuthunyelwa kwedatha yokulinganisa: Impendulo ye-impulse njengefayela le-.wav namanani alinganiselwe nge-CSV kanye nefomethi ye-.FRD efinyelelekayo
- Ukuthunyelwa kwempendulo yemvamisa kanye nesigaba ngefomethi ye-.FRD (ivumela ukungenisa nokuqhubeka nokucubungula ngezinhlelo eziningi zokulinganisa umsindo)


Zonke izilinganiso
- Ukusetshenziswa kwemibhobho yokulinganisa (ukungenisa kwejika lokulinganisa)
- Amathuba wokulinganisa we-microphone eyakhelwe ngaphakathi ngezilinganiso zokuqhathanisa, uma umbhobho wokulinganisa utholakala.
- IsiNgisi nesiJalimane
