数据压缩器 meaning in English

data compre or
dc data compressor

In the digital ultrasonic flaw detectors , backward - wave signal is sampled and changed through the highspeed a / d converter , and we ' ll get a large number of datas . because datas are not all be used to draw testing curve , they must be compacted . lt is necessary to compress so much datas , so data - compaction instrument must be designed and used . here introduces the principle of data - compaction instrument , and designs a exclusive instrument using isp which may change compression point and automatically provide 1024 consecutive addresses of outside data storage unit
在数字化超声波探伤中，回波信号经高速a d采样变换后，会得到大量的采集数据。但在探伤曲线的描绘中并不是用到所有数据，因此要对这些数据进行压缩处理，这就需要用到数据压缩器，这里介绍了一种应用在线可编程技术及器件实现对大量采样数据进行快速压缩的方法，并设计了一种新型的专用isp数据压缩器，该压缩器具有压缩点数可调，可自动提供1024个连续的外部数据存储单元的地址等特点。
