In one embodiment, an apparatus may include a pulse generator to generate an oversampled clock signal. 02cm2 or less, and an epitalial wafer wherein an epitaxial layer is formed on the silicon wafer for epitaxial growth. These basis functions may be generated from analytical functions andor empirically measured spectral data and produce output shape calibration templates that are independent of the generation method for the basis templates. In the terminal, at least two independent signals that comprise at least a channel distorted version of the transmitted block are generated. A resist layer is applied on the conductive layer and has a set of openings for exposing a portion of the conductive layer covering some of the electrical connection pads.
