Even when discretizing the Muskingum model using the zero-order hold method, another problem appears when selecting the sampling time period satisfying the rule given in (9) in order that the discrete Muskingum model has hydrological meaning since the Shannon theorem [54] is not respected.
For the purpose of comparison of simulated and measured data values of massive "vihod" are transmitted to the scope through Zero-Order Hold for their digitization (please see Fig.
Perhaps the first attempt to study discrete system zeros was given by Astrom and coworkers [1], who describe the asymptotic behavior of the discrete-time zeros for fast sampling rate when the original continuous-time plant is discretized with zero-order hold (ZOH).
