dfds

In DFDs, the interface passes data.

在DFD中，这个接口传递数据。

FM/ FM telemetry systems have been widely used in many aspects, so it is very important to study Digital FM/ FM Demodulating System ( DFDS).

FM/FM遥测体制有着广泛的应用，研究数字式FM/FM解调系统具有重要意义。

In many ways, activity diagrams are the object-oriented equivalent of flow charts and data-flow diagrams ( DFDs) from structured development.

在很多方面，活动图是结构化开发中流程图和数据流程图（DFD）的面向对象等同体。

Object-flow diagrams ( OFDs) are similar to data-flow diagrams ( DFDs), because they depict activities interfacing with other activities.

对象流图（OFD）与数据流图（DFD）类似，因为它们描述了活动和其他活动间的接口。

Demultiplex filter ( usually refers to bandpass filter) is a significant part of DFDS, while the flat frequency response and linear phase characteristic in the passband of the FIR filter make it the best choice for the system.

分路滤波器（通常是带通滤波器）是解调系统的重要组成部分，有限冲激响应（FIR）数字滤波器具有平坦的通带幅度响应和线性相位特性，是数字式解调系统的最佳选择。
