I've did some more checking of both documentation and code and I might have found a bug in the RSM Table instance. I have also posted the discussion "RMS Table Problem" yesterday on the forum. I have build a dynamic processor with look ahead function in my project and also here I have found an invalid readback; I have filled the table with all 1 (5.23 format) meaning flat responce. However, when there is no input signal, the output of the RMS Table is 0. I've attached a screenshot again!
