GradientAdaptiveLattice
ptolemy.actor.lib.GradientAdaptiveLattice

An adaptive FIR filter with a lattice structure. This class extends the base class to dynamically adapt the reflection coefficients to minimize the power of the output sequence. The output reflection coefficients are guaranteed to lie between -1.0 and 1.0, ensuring that the resulting filter is a minimum phase linear predictor. The reflectionCoefficients parameter is interpreted as the initial coefficients.

adaptedReflectionCoefficients
The output port that produces the current reflection coefficients. The port is of type array of double.



timeConstant
The time constant of the filter, which determines how fast the filter adapts. The default value of this parameter is 1.0.
