ABSTRACT:
A method of transforming an analog electrical signal into a wavelet transform. The analog electrical signal is input into a transmission line system as a transmission line input signal. A wavelet transform lifting is performed on the transmission line input signal to provide at least a first sum signal and a first difference signal of the transmission line input signal. The sum signal is designated as a first wavelet transform approximation signal and the difference signal is designated as a first wavelet transform detail signal.
