Analysis of method to eliminate undesired responses in a binary phase-only filter
暂无分享,去创建一个
Several methods have been suggested for eliminating the undesirable convolutional and high-order-response terms in a binary phase-only filter (BPOF) (e.g., Zhang, Su, and Guo in 1987 and Davis, Cottrell, Davis, and Lilly in 1989). We show how our previously published (in 1992) analysis of the basic BPOF can be applied to these methods.
