  An unfolding method, based on Bayes theorem is presented to obtain true
event-by-event net-charge multiplicity distribution from a corresponding
measured distribution, which is subjected to detector artifacts. The unfolding
is demonstrated to work for widely varying particle production mechanism, beam
energy and collision centrality. Further the necessity of taking into account
the detector effects is emphasized before comparing the experimental
measurements to the theoretical calculations, particularly in case of higher
moments. The advantage of this approach being that one need not construct new
observable to cancel out detector effects which loose their ability to be
connected to physical quantities calculable in standard theories.
