# laplace transform and z transform

Laplace Transform can be converted to Z transform by the help of bilinear Transformation . This transformation gives relation between s and z . s=(2/T)*{( z1)/( z +1)} where, T is the sampling period.In summary, the z transform (times the sampling interval T) of a discrete time signal xd(nT) approaches, as T → 0, the Laplace Transform of the underly- ing continuous-time signal xd(t). For the mapping z = esT from the s plane to the z plane to be invertible, it is necessary that X(jωa) be zero for all |ωa| ≥ π/T.
