    • In a system for processing PCM signals and transmitting such signals over a channel, which system includes an input portion having a circuit for interleaving arriving data words and supplying the interleaved words to the input end of the channel, and an output portion having a circuit for de-interleaving the data words arriving at the output end of the channel so that the data words, after de-interleaving, are present in the sequence existing before interleaving, the interleaving circuit performs two successive interleaving operations on the arriving data words, and the de-interleaving circuit operates in a manner to complement the interleaving circuit.
    • 在用于处理PCM信号并通过信道发送这样的信号的系统中,哪个系统包括一个输入部分,该输入部分具有用于交织到达的数据字的电路并将交错的字提供到该信道的输入端,以及一个输出部分, 对到达信道的输出端的数据字进行解交织,使得解交织之后的数据字存在于交织之前存在的序列中,交织电路对到达的数据字执行两个连续的交织操作, 解交织电路以交织电路补充的方式工作。
