Wavelet Analysis

5-533

n-1

output samples, before propagating the first analyzed input sample

(computed from the input received at t=0).

See “Excess Algorithmic Delay (Tasking Latency)” on page 3-91 and “The

Simulation Parameters Dialog Box” in the Simulink documentation for more

information about block rates and Simulink’s tasking modes.

Dialog Box

The parameters displayed in the dialog box vary for different wavelet types.

Only some of the parameters listed below are visible in the dialog box at any

one time.

Wavelet name

The wavelet used in the analysis.

Wavelet order

The order for the

Daubechies, Symlets, and Coiflets wavelets. This

parameter is available only when one of these wavelets is selected in the

Wavelet name menu.

Filter order [synthesis / analysis]

The filter orders for the synthesis and analysis stages of the

Biorthogonal

and Reverse Biorthogonal wavelets. For example, [2/6] selects a

second-order synthesis stage and a sixth-order analysis stage. The

Filter

order

parameter is available only when one of the above wavelets is

selected in the

Wavelet name menu.

Number of levels

The number of filter bank levels. An n-level structure has n+1 outputs.
