WIP窗口是一个极其动态的环境；版本的有关信息在WIP中频繁变化，用以反映何时调度转换步骤以及执行进度如何。
The WIP window is a very dynamic environment; information about editions very frequently changes in the WIP, to reflect when the transformation steps are scheduled, and how the execution progresses.
传统双上变频发射器通常采用中频(IF)混合器和射频(RF)混合器将基带用户信号依次转换成IF和RF。
Conventional dual up-conversion transmitter usually employs an intermediate frequency (IF) mixer and a radio frequency (RF) mixer to convert baseband user signal to IF and RF in sequence.
这种直接转换接收器能够免除进行中频(IF)滤波的需要。
This direct conversion receiver can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding requirements for image filtering and IF filtering.
软件无线屯的设计思想之一是将A／D转换器尽可能靠近天线，即把A／D从基带移到中频甚至射频，把接收到的模拟信号尽早数字化。
One of the important conceptions of Software Radio is to make A/D converter close to antenna, we should convert IF analog signal even RF analog signal into digital signal.
