Abstract:
1. A method for producing a system for representation of an electrical network, comprising: providing the electrical network having an input and an output, wherein the electrical network has a non-linear transmission response; supplying an input signal to the input of the electrical network, wherein the input signal has an input signal bandwidth, and providing an output signal at the output of the electrical network, wherein the output signal has an output signal bandwidth; sampling the output signal at a frequency that is derived from the input signal bandwidth and is less than a value equal to twice the output signal bandwidth, thereby producing a sampled output signal; supplying a digital baseband signal to an initial model associated with the electrical network and producing a digital baseband output signal therefrom, wherein the digital baseband signal is derived from the input signal; comparing the digital baseband output signal with the sampled output signal and determining parameters to update said initial model to generate an updated model based on the comparison, wherein the determined parameters minimize an error between the digital baseband output signal output from the updated model and the sampled output signal; and generating an interpolated model based on the updated model by performing an interpolation operation on the updated model, wherein the interpolated model is for correction of the low sampling rate and consideration of the signal components outside the useful signal spectrum in the output signal of the electrical network.
