companding 压扩(法,技术) 1.A process in which compression is followed by expansion. 在压缩之后接着进行扩展的一种处理过程。 2.Data in bits can often be recorded into a more compact form for transmission, using a compaction algorithm. A related algorithm can recover the original form; the entire sequence represents companding. 二进制数据在传输时利用压缩算法进行压缩,接收后用相应的算法使其恢复到原来的形式,这整个过程叫压扩处理法。 3.In voice transmission, to compress the signal amplitude into a narrow range be cause the amplifiers are linear over wide ranges. 在话音通信中,因放大器的线性范围有限,把信号幅度压缩到一个较小范围的处理。 |
