Using of complicated big (robust) electronics analog systems, its function then efficient, if the electronic circuit is certain his behavior, its certain parameters, the changed according to conditions, we can modify it. If we place an embedded controller in the environment of the analogous system, that for us important parameters values it, then the controller because of depends of an algorithm, it may intervene in the function of an analogous electronic circuit. We place one or more field programmable analog array (FPAA) if it is analogous in an electronic circuit system, on suitable places, then these parametrical and you are topology configuring we may intervene very efficiently.
