    摘要: Apparatus for interpolating data along radial lines so that it can be displayed at display points arranged in orthogonal rows and columns by recursively adding stored values to derive signals indicative of the radial position of each display point along the radial data lines and its angular position between the radial data lines. Interpolation is done along each radial line to derive first and second intermediate interpolated values, and these values are interpolated so as to derive the final data value for the display point at its angular position. Alternatively, the intermediate interpolated values can be attained by angular interpolation and the final data value by radial interpolation.

    摘要: Apparatus for displaying the information represented by data samples occurring along radial lines at display points arranged in rows and columns wherein intermediate interpolated data values are derived at the intersections of a row containing a display point for which a final data value is sought with radii on either side of the display point and interpolating the first and second intermediate interpolated data values so as to derive a final interpolated data value at the angular position of the display point with respect to the radii.
