A Fully Multiplexed First-Order Frequency-Planar Module for Fan, Beam, and Cone Plane-Wave Filters

A VLSI architecture for the on-chip realization of a first-order two-dimensional (2-D) or three-dimensional (3-D) infinte impulse response (IIR) fully multiplexed frequency-planar filter module (FMFPM) is proposed. Such filter modules may be used in 3-D video processing and 2-D/3-D plane-wave filtering using sensor arrays. The proposed FMFPM can potentially be used as a 2-D/3-D IIR building block circuit for the on-chip realization of second- (or higher) order frequency-planar filters, 3-D IIR beam filters, 2-D IIR fan filter banks and 3-D IIR cone filter banks
