Noncausal recursive filters have recently been proposed because of their increased efficiency versus linear phase FIR filters and causal IIR filters [2]. A general frequency domain design technique capable of exploiting the characteristics of noncausal filters is not yet available. This paper proposes the use of multiple criterion optimization for the frequency domain design of noncausal IIR filters. A new family of filters is generated and their efficiency versus causal FIR filters and IIR filters is discussed.
