WebAboutTranscript. The graph y=k⋅f (x) (where k is a real number) is similar to the graph y=f (x), but each point's distance from the x-axis is multiplied by k. A similar thing happens when we graph y=f (k⋅x), only now the distance from the y-axis changes. These operations are called "scaling." A wavelet is a wave-like oscillation with an amplitude that begins at zero, increases or decreases, and then returns to zero one or more times. Wavelets are termed a "brief oscillation". A taxonomy of wavelets has been established, based on the number and direction of its pulses. Wavelets are imbued with … See more The word wavelet has been used for decades in digital signal processing and exploration geophysics. The equivalent French word ondelette meaning "small wave" was used by Morlet and Grossmann in the early 1980s. See more Wavelet theory is applicable to several subjects. All wavelet transforms may be considered forms of time-frequency representation for continuous-time (analog) signals and so are … See more The wavelet transform is often compared with the Fourier transform, in which signals are represented as a sum of sinusoids. In fact, the Fourier transform can be viewed as a special case of the continuous wavelet transform with the choice of the mother wavelet See more The development of wavelets can be linked to several separate trains of thought, starting with Haar's work in the early 20th century. Later work by Dennis Gabor yielded Gabor atoms (1946), which are constructed similarly to wavelets, and applied to similar … See more For practical applications, and for efficiency reasons, one prefers continuously differentiable functions with compact support as mother (prototype) wavelet (functions). However, to satisfy analytical requirements (in the continuous WT) and in general … See more A wavelet (or a wavelet family) can be defined in various ways: Scaling filter An orthogonal wavelet is entirely defined by the scaling filter … See more A wavelet is a mathematical function used to divide a given function or continuous-time signal into different scale components.
