Abstract

Usually filtering and sampling devices for optoelectronic signals consists of low-pass filters represented by an asymptotically stable system (of first or second order). Many times an integration of the filter output over a certain time interval is added. However, such a structure is very sensitive at the random variations of the integration period. This paper will show that for obtaining a filtering and sampling device less sensitive at these random variables we have to use a filter represented by an oscillating system. Mathematical aspects connected with the number of state-variables are also presented.
