DESCRIPTION

The L2330 is a coordinate transformer that converts bidirectionally between Rectangular and Polar coordinates. When in Rectangular-to-Polar mode,

the L2330 is able to retrieve phase and magnitude information or backward map from a rectangular raster display to a radial data set.

When in Polar-to-Rectangular mode, the L2330 is able to execute direct digital waveform synthesis and modulation. Real-time image-space conversions are achieved from radially-generated images, such as RADAR, SONAR, and ultrasound to raster display formats.
