| Abstract: | One design method of composite video signal generator using high-speed D/A converter was proposed. A summarized review of composite video signal in case of PAL was provided. More attention was paid on difficulties in the design and corresponding solutions, such as continuity of the phase of sub carrier, image room and interpolating. |
