“…Previous work on sampling error for linear-constant coefficient systems is represented by the work of Sklansky and Ragazzini [1], Muira [2], and Gilbert [3]. The limited literature concerning sampling error in more general systems is characterized by the "sensitivity" approach of Miller and Murray [4] and Karplus [5] and by the explicit error equations developed by Hammond and Finn [6], elaborated on by Hammond and Alford [7] and Alford [9].…”

features for identification purposes, in order to encourage readers with more available resources to pursue the matter further.It is suggested that numerous samples from numerous different handwritings be taken, with the processing based on the statisti cal approach described in Section III-A. REFERENCES [1] M. Eden, "Handwriting and pattern recognition," IRE Trans.Abstract-A hybrid closed-loop system consists of a combination of continuous and discrete elements. Such systems are common in hybrid computer simulation or digital implementation of continuous controllers. The signal conversion process introduces errors into the system when compared with an equivalent system based on continuous variables. These errors, called sampling errors, are a function of several parameters within the digital part of the system. A model for these errors that can be used to estimate the effects that a particular hybrid implementation will have on the system response is developed in this work. An example is given to illustrate the application and accuracy of the equations.
