"Overtone" yog ib lo lus feem ntau siv rau txhua qhov ntau zaus sawv nthwv dej, thaum lub sij hawm sib haum xeeb yog tshwj tseg rau cov xwm txheej uas cov zaus ntawm overtones yog qhov sib npaug ntawm ntau zaus ntawm qhov fundamental.
Puas yog tag nrho cov kev sib raug zoo?
Txhua yam kev sib haum xeeb yog overtones rau kab qhib cua lossis hlua. Kaw cua kab tsim tsuas yog khib harmonics. Ib daim nyias nyias ua kom muaj kev sib haum xeeb, tab sis kuj tseem muaj lwm cov overtones.
Dab tsi yog qhov zaus ntawm overtones?
Ib qho kev tshaj tawm yog txhua zaus ntau dua qhov tseem ceeb ntawm lub suab. … Siv tus qauv ntawm Fourier tsom xam, lub hauv paus thiab cov overtones ua ke yog hu ua partials.
Puas muaj qhov sib txawv ntawm kev sib haum xeeb thiab kev tshaj tawm?
Qhov sib txawv tseem ceeb ntawm kev sib haum xeeb thiab kev sib tw yog qhov overtones xa mus rau ib qho resonant zaus ntawm lub kaw lus uas muaj zaus siab dua nws qhov zaus zaus thaum lub sij hawm harmonics xa mus rau resonant frequencies uas yog integer multiples of the fundamental zaus.
Yuav ua li cas koj xam harmonics ntawm overtones?
