Title: Chroma generation system

Abstract: A chroma generation system provides the six major discrete colors in a NTSC color television system. This is achieved simply and inexpensively by a pair of resonant circuits which shift a fundamental color subcarrier signal by lead and lag relationships to provide yellow and magenta colors, respectively, and also provides the proper magnitudes so that when the vectors are combined, a red signal results. The fundamental color signal when inverted provides the complements of the foregoing colors to thus provide the six different discrete saturated colors.
