ABSTRACT:
A method and apparatus for modeling and synthesizing the response of a network to selected input signals where the input signals may be multi-channel in analog or digital form, and where the network's response may be linear or non-linear and depend on the present input signals as well as its past responses. A relationship is established between the input signals and the network's response to the input signals. Basis vectors are selected capable of representing the relationship. Weighting values for each basis vector are calculated. The calculated weighting values are applied to the corresponding basis vectors to form weighted basis vectors. The synthesis and modeling are then performed by forming a linear combination of the weighted basis vectors. Provision is made for feeding back the linear combination to account for memory and other history-dependent responses of the network.
