Web21 dec. 2024 · Wavelets have two basic properties: scale and location. Scale (or dilation) defines how “stretched” or “squished” a wavelet is. This property is related to frequency as defined for waves. Location defines where the wavelet is positioned in time (or space). Example Wavelet: The first derivative of Gaussian Function. Image by author. Web9 apr. 2024 · Conditions include that the wavelet is a nonzero in a limited interval and that the integral of the wavelet must be zero. (1) ∫ ψ (x) d x = 0.
