Abstract
We introduce a novel design criterion for data-dependent narrowband filters that are of interest in temporal or spatial spectral analysis applications. The solution to the design problem considered is shown to coincide with the recently introduced amplitude and phase estimation (APES) filter. The new derivation of APES in this note sheds more light on the properties of APES and provides some intuitive explanation of the performance superiority of the APES filter over the Capon filter.
