Wavelet Synthesis
5-539
Latency
Zero Latency. The Wavelet Synthesis block has no tasking latency for
frame-based operation, which is always single-rate. The block therefore uses
the first input samples (received at t=0) to synthesize the first output sample.
Nonzero Latency. For sample-based operation, the Wavelet Synthesis block is
multirate and has the following tasking latencies:
•2
n
-2 samples in Simulink’s single-tasking mode
•2
n
samples in Simulink’s multitasking mode
In the above cases, the block repeats a zero initial condition in each channel for
the first D output samples, where D is the latency shown above. For example,
in single-tasking mode the block generates 2
n
-2 zero-valued output samples in
each channel before propagating the first synthesized output sample
(computed from the inputs 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.
