  This document describes the early stage of the reconstruction chain that was
developed for the ArgoNeuT and MicroBooNE experiments at Fermilab. These
experiments study accelerator neutrino interactions that occur in a Liquid
Argon Time Projection Chamber. Reconstructing the properties of particles
produced in these interactions requires knowledge of the micro-physics
processes that affect the creation and transport of ionization electrons to the
readout system. A wire signal deconvolution technique was developed to convert
wire signals to a standard form for hit reconstruction, to remove artifacts in
the electronics chain and to remove coherent noise.
