emäaaltofunktiota
emäaaltofunktiota refers to the mother wavelet in wavelet analysis. Wavelets are mathematical functions used to decompose a signal into different frequency components. The mother wavelet serves as a prototype from which all other wavelets in a particular wavelet family are derived through scaling and translation. These derived wavelets are called child wavelets. The choice of mother wavelet significantly influences the properties of the resulting decomposition and is crucial for applications such as signal compression, denoising, and feature extraction. Different mother wavelets possess distinct characteristics, such as their shape, symmetry, and smoothness, which make them suitable for analyzing different types of signals and detecting specific features. Common examples of mother wavelets include the Haar wavelet, the Daubechies wavelets, and the Morlet wavelet. The process of selecting an appropriate mother wavelet often involves considering the nature of the signal being analyzed and the desired outcome of the wavelet transform.
