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 specific properties that make them useful for signal processing. thumb|Seismic wavelet
Wavelet o ondicelle, analisi wavelet, e trasformata wavelet si riferiscono alla rappresentazione di un segnale mediante l'uso di una forma d'onda oscillante di lunghezza finita o a decadimento rapido (nota come wavelet madre). Questa forma d'onda è e traslata per adattarsi al segnale in ingresso.
