Zaus Qhov Kev Ntsuas - Qhov Kev Xam Theem Pib ntawm FFT Qhov Kev Ntsuas Ntau zaus. DSA, feem ntau xa mus rau Dynamic Signal Analysis lossis Dynamic Signal Analyzer raws li lub ntsiab lus teb, yog thaj chaw thov ntawm lub teeb liab digital processing technology. ... Lub FFT pauv lub sijhawm sau npe mus rau hauv zaus zaus.
DSA, feem ntau xa mus rau Dynamic Signal Analysis lossis Dynamic Signal Analyzer raws li lub ntsiab lus teb, yog thaj chaw thov ntawm lub teeb liab digital processing technology. Muab piv rau cov ntaub ntawv dav dav thiab lub sijhawm tshawb xyuas lub sijhawm, DSA cov cuab yeej thiab cov cuab yeej ua lej tsom rau ntau qhov sib txawv ntawm cov teeb liab xws li cov lus teb zaus, ntau qhov kev cuam tshuam, tag nrho cov kev tsis sib haum, qib sib luag, cov dav dav thiab ntau ntxiv .. Xyoo tsis ntev los no, sijhawm sau cov ntaub ntawv kis cov khoom siv thiab DSA cov twj paj nruag tau maj mam sib hloov ua ke. Ntau thiab ntau lub sijhawm sau cov twj paj nruag, xws li oscilloscopes, tuaj yeem ua qhov ntsuas zaus thaum ntau thiab ntau cov teeb meem sib zog tau ntsuas tau cov ntaub ntawv ntev ntev.
DSA siv ntau yam txuj ci thev naus laus zis ntawm lub teeb liab digital. Ntawm lawv, cov feem ntau theem pib thiab nrov tshuab yog ua raws li lub npe hu ua Kev Tshaj Plaub Tauj Hloov Ceev (FFT). Tus FFT pauv lub sijhawm sau npe mus rau hauv zaus zaus. Txhawm rau ua qhov ntsuas FFT-raws li kev ntsuas, txawm li cas los xij, koj yuav tsum nkag siab txog cov teeb meem tseem ceeb thiab cov kev suav suav. Tshooj Lus no piav qee qhov pib teeb tsa cov teeb meem tsom xam, sib tham txog kev tawm tsam thiab rov qab los tom ntej rau FFT-based teeb liab tsom xam, piav qhia txog kev siv cua tshuab ua haujlwm kom raug, piav qhia qee qhov ntsuas spectrum, thiab qhia koj siv FFT-based ua haujlwm li cas rau qee qhov kev ntsuas raug.
Hauv Tshooj Lus no peb yuav siv cov cim taw qhia rau cov cim sib txawv. Txhua yam ntawm lub teeb liab yuav sawv cev los ntawm ib tsab ntawv tshwj xeeb. Piv txwv li, "G" sawv rau lub zog ntawm ib sab, thaum "H" sawv cev rau txoj haujlwm hloov tsheb.
Cim npe nrov: cov kws tsom xam cov ntaub ntawv dynamic thiab FFT, tuam ntxhab, yuav, tus nqi qis, hauv Tshuag
