RGB encoder for converting digital signals to analog signals and activating deactivating D/A converters according to a mode signal |
摘要 |
An encoder converts digital RGB signals into analog television signals. This encoder forms digital composite, luminance and chrominance signals based on digital signals input through an RGB input terminal. The encoder has a first, a second and a third D/A converters for converting digital composite, luminance and chrominance signals into corresponding analog signals. The encoder is provided with a switch for activating required ones of the three D/A converters and deactivating others of the D/A converters.
