recording channel

The transmitting channel implements the voice recording, spectrum spreading and BPSK modulation while the receiving channel implements the BPSK demodulation, code dispreading and voice broadcasting.

该系统是双通道的，发送通道实现话音的录入、扩频和BPSK调制发送，接收通道实现话音的BPSK解调接收、解扩和播放。

Except the regular field setup parameters were used, in order to ensure the complete data collection, measures of ″ use recording channel to make up insufficient shotpoint, bilaterally shotpoint added, split shooting added ″ were adopted, thus rather satisfied data were collected.

观测系统除采用了规则观测系统参数外，还采用了以道补炮、双边加密炮点、中间激发加密炮点的方法，确保了勘探区内资料齐全，取得了较满意的观测数据。

Radio, by contrast, uses an oral channel and spoken language and relies on technologies of sound recording and broadcasting, whilst television combines technologies of sound-and image-recording and broadcasting.

广播，相反，则运用口头的表达方式，依靠录音和广播技术来完成内容。电视却结合声音和图像录音技术和广播。
