Wavelet analysis: graphical display

• High frequency components appear at the location of the jumps
• Low frequency compoents appear everywhere, as they should
• A fourier transform would show the components but not where in time they occur

Schematic display:

• For example, the d1 line shows that a very narrow wavelet will be included in the result at two locations; inverted in the second case.
• The s6 line shows that several instances of a very broad wavelet will be added in different amounts.
• This will be discussed further in the next example.
