Linear operations performed in one domain (time or frequency) have corresponding operations in the other domain, which are sometimes easier to perform. The operation of differentiation in the time domain corresponds to multiplication by the frequency, so some differential equations are easier to analyze in the frequency domain. Also, convolution in the time domain corresp… WebFeb 14, 2024 · The objective of this study was to characterize the major sources of variation in the absorbance of the infrared spectrum in caprine milk samples.
