Filter for state variables

摘要

The invention relates to a second-order filter for state variables, with identical coefficients a11 and a22 of the state transition matrix, and is characterised by a common feedback loop for the two delay sections, the output signals of which are combined by means of a further adder, weighted and supplied to the two inputs of the delay sections. The advantage lies in that there is no multiplication and thus no multiplier and only an addition is added which is easier to implement and can be carried out faster. <IMAGE>
