ABSTRACT:
A visual plot of a single valued function is rotated orthogonally and then iewed by a TV camera. The camera output is recorded on a video recorder and then played back to a digitizer. The digitizer horizontally scans the rotated plot and detects the time interval for each horizontal scan to intersect a respective point on the rotated plot. The intervals correspond to the amplitude of different points along the plot. The information derived may be stored for subsequent data processing.
