A general approach to deriving the z-domain transfer function H(z) for a discrete-time system
intended to approximate a linear continuous-time system with transfer function H(s) is now given.
Starting with a simulation diagram of the continuous-time system, each integrator block with
transfer function H
I
(s) ¼1=s is replaced by a discrete-time transfer function block H
I
(z) correspond-
ing to a specic numerical integrator. For example, replacing H
