  In this paper we have adapted Bahl and Tuteja (1991) estimator in systematic
sampling using auxiliary information. Using Bedi (1996) transformation an
improved estimator is also proposed under systematic sampling. The expressions
of bias and mean square error up to the first order of approximation are
derived. It has been shown that the proposed estimator performs better than
many existing estimators. A numerical example is included to support the
theoretical results.
