Lub hwj chim tseem ceeb txhais
Lub hwj chim sai yog hais txog lub hwj chim uas lub cev hluav taws xob nqus ib pliag hauv physics. Nws qhov ntau ntawm yog sib npaug nrog cov khoom lag luam ntawm tus nqi hluav taws xob instantaneous voltage thiab tam sim no. Lub zog hluav taws xob nrawm nrawm nrawm nrawm vim hais tias qhov ntsuas hluav taws xob thiab qhov tam sim no yog cov tsis sib xws ntawm cov qauv sine yoj vim qhov tsis nrawm rau hauv lub zog fais fab. Lub tswv yim qub ntawm kev sib raug zoo sib cais voltage thiab tam sim no los ntawm Fourier orthogonal decomposition, uas tsis tsuas yog nyuaj rau pom tias txoj kab sib txuas ntawm qhov hluav taws xob thiab qhov tam sim no zoo, tab sis vim tias muaj cov nquag thiab cov khoom siv cuam tshuam rau txhua lub xaim hluav taws xob. tau yooj yim superimposed rau tag nrho cov kev ua haujlwm thiab lub zog, uas ua rau muaj kev nyuaj ntawm lub zog tsom.
