Additionally, we can also use a • Continuous time systems piecewise linear approximation • Laplace transforms ∞ t- nT ∞ t- nT Z transforms x c ( t ) = x d [ n ] a + x d [ n + 1] c (2) • T T Numerical methods n =-∞ n = ∞ • where a and c are the right- and left-sided unit triangles functions, respectively.
