• Backward Euler. The backward Euler method is very similar to forward Euler, but it has a different time delay: When applied to the derivative y (t) = d d t x (t), the forward Euler method results in the discrete-time recurrence relation y [k] = x [k + 1] − x [k] T s, which is non-causal (the output y [k] depends on the future input x [k + 1]).
