随着数字电视技术的迅速发展,各种电视设备的数字化已呈必然趋势,这就迫切需要有高精度的数字图象信号源作为调整和监测。我所为满足这种需要,已研制成功一种全数字化的彩色/黑白图象信号发生器。该仪器具有准确度高、稳定可靠、抗干扰性强、无调整元件等优点,能产生出符合国家标准100/0/75/0彩条信号数据流,还能产生红、绿、兰三基色信号和黑白条;棋盘、灰度条,锯齿信号等数据。视频数据字长为八位。机内附有
With the rapid development of digital television technology, the digitization of various television equipment has shown the inevitable trend, which urgently needs a high-precision digital image signal source as the adjustment and monitoring. To meet this need, I have developed a fully digital color / black and white image signal generator. The instrument has the advantages of high accuracy, stable and reliable, strong anti-interference, no adjustment components, etc., can produce a color flow signal line in line with the national standard 100/0/75/0, but also produce three primary colors of red, green and blue Signal and black and white; chessboard, grayscale, sawtooth signal and other data.
