Power signals are signals with finite power, and energy signals are signals with finite energy (Anstey, 1958[1]). A wavelet is defined as an energy signal that is concentrated in a certain time interval. As a result, an arrival time, or origin time, can be associated with a wavelet. The arrival time is the reference point of the wavelet and usually is designated as time zero. Thus, a wavelet is a signal characterized by two properties:
