Basic formula is ch = K log (S) where ch is the logged channel value, S is the linear signal, and K is a scaling constant. For a 4 decade log amp and 8 bit channel resolution (0-255 channels), K= 64. >Hello to All, > >There is a simple formula for converting log data to linear, and I have >forgotten.
