Direct digitization of the signals and following data treatment using math. algorithms

Idea of one unique „Digital BPM analysis electronics“ for all GSI accelerators (and others....)

New BPM System SetupIdea: Use of modern digital signal processing electronics using fast 12/14-bit 100-250 MSa/s ADCs, DSPs and FPGAs and a „software“ capable to treat (more than) 1 MB/ms raw data of the BPMs!
