  • Abstract
    Several second-order digital filter structures have been proposed recently, which possess excellent sensitivity characteristics and which are free from zero-input limit cycles. It is shown in this letter that by making some simple modifications, these filter structures can be stabilised against constant-input limit cycles as well.
