	In this paper, starting from the basic description of the equation that governs the bunch motion and looking at the advances of the technology, three examples of feedback designs versus technology trend are presented and discussed. In particular the author compares three digital systems implemented or proposed for DAFNE and other e+/e- accelerators. Descriptions of some relevant features are also done. Conclusions on the digital feedback design trend are reported.
