  We report the results of broadband timing and spectral analysis of data from
an AstroSat observation of the High Mass X-ray binary LMC X$-$4. The Large Area
X-ray Proportional Counter (LAXPC) and Soft X-ray Telescope (SXT) instruments
on-board the AstroSat observed the source in August 2016. A complete X-ray
eclipse was detected with the LAXPC. The 3$-$40 keV power density spectrum
showed the presence of coherent pulsations along with a $\sim 26$ mHz
quasi-periodic oscillation feature. The spectral properties of LMC X$-$4 were
derived from a joint analysis of the SXT and LAXPC spectral data. The 0.5$-$25
keV persistent spectrum comprised of an absorbed high energy cutoff power law
with photon index of $\Gamma \sim$ 0.8 and cutoff at $\sim$16 keV, a soft
thermal component with kT$_{BB} \sim$ 0.14 keV and Gaussian components
corresponding to Fe K$_\alpha$, Ne \textsc{ix} and Ne \textsc{x} emission
lines. Assuming a source distance of 50 kpc, we determined 0.5--25 keV
luminosity to be $\sim 2 \times 10^{38}$ erg s$^{-1}$.
