  The DFT representation is applied, to a ordered-chaotic finite-duration
sequences set generated by the H\'enon mapping, for describing the order-chaos
transition. This representation has the advantage that it may be applied to a
relatively shorter discret-time series. The bifurcation diagram is produced and
the largest Lyapounov exponent is calculated for each time series of the set,
showing a good agreement with the results obtained by the DFT representation.
The threshold value of the control parameter for the order-chaos transition was
determined to be A=1.0532.
