At present, the measurement of sluice gate opening usually USES the digitalencoder. It has the advantage of high measuring precision and USES the absolute coding method which makes it widely used.
目前水库闸门开度测量通常使用的是数字编码器，它的测量精确度高且使用绝对编码技术，得到广泛的应用。

Modern encoders are not only used in the CD-ROM area, but also as a means of transmitting signals, they use a number of digital signal processor to form a vision encoder.
The serial digital high definition video signal will be used as an input source for high definition encoder and generate high definition video programs.
