WebThe sinusoidal functions are actually called basis functions, the implicit assumption is that the basis functions map well to the signal components. As such, the Haar wavelets are binary basis functions. There is (theoretically) an infinite range of basis functions. Discrete signals can map better into collections of binary components rather ... WebThere are two types of situation in which it is particularly useful to think of a time series of observations as a sum of sinusoids: When one knows, based on physical considerations, that the big signal really is very accurately expressed as a sum of a few sinusoids of known frequency. The tides are a perfect example; astronomical forcing ...
