Abstract
A circuit for interpolating discrete data points or horizontal line segments of a single valued function in one direction into a continuous line display. So that only one value need be produced from a memory for each display position along one axis of an x,y coordinate system display, the circuit generates lines parallel to the other axis which connect the display at adjacent positions along the first axis. The circuit receives and displays a line of data; delays the line of data by one clock pulse and displays the delayed line; compares the line and delayed line to determine the ends of data in the line; stores the position of the ends of data in a shift register; displays the output of the shift register; and returns the output of the shift register to the input of the shift register for each end position until data is received in a position adjacent the end position.
