Abstract :
The addition of an optional feedback loop to a previously described automatic analog curve reader, which was originally designed for reconversion of EEG ink recordings to electrical form, permits operation of the curve reader as a true line follower, often a more appropriate method for reconversion of polygraphic ink recordings having gradual to moderate slopes.
