A method of representing data in magnetizable surface storage; for example,"modified frequency modulation".

在存储技术中一种示数据的方法，例如改进型调制。

The Configuration and activity theoretical of the placet frequency modulation glary instrument are introduced in this paper.

本介绍了一种新型的可调闪仪的结构及其工作原理。

The motion picture on the videodisk is encoded as frequency modulation, and the audio signal is mixed with the video signal.

视的视信号以调方式编码，音信号混入视信号中。
