您要查找的是不是：
- negative going sync pulse 负向同步脉冲
- positive going sync pulse 正向同步脉冲
- The display system "looks" for the zero crossing of the sync pulse. 终端显示系统将识别这个同步脉冲的过零跳变。
- positive going sync pulses 正向同步脉冲
- A significant amount of power is used by the broadcast transmitter to send the sync pulse. 由于大量的功率被广播发射机用来发送同步脉冲，一般将视频信号的极性设计为在传送同步信号降低功耗的方式。
- Looking for the sync pulse has always been one of the "trickiest" of tasks for the display signal processor. 对于显示信号处理器来说，寻找同步脉冲一直都是一项十分重要的工作。
- Lots of negativity going on right now. 最近有太多的负面报道。
- Each half of the tri-level sync pulse is defined to be 44 samples (reference clock periods) wide, for a total sync pulse width of 88 samples. 每一半三同步脉冲定义为44个采样时钟周期的宽度，所以一个完整的三电平同步信号的宽度为88个采样周期。
- HSPW：TFT: Horizontal sync pulse width determines the HSYNC pulse's high level width by counting the number of the VCLK. 这个问题我也不大清楚啊！设置什么电平有效？电平保持多久才能被当成是有效的信号？
- It requires careful biasing of the sync processing circuitry so that the sync pulse is made as distinguishable as possible from the other voltage levels within the video signal. 为了能够方便的将同步脉冲从包含着许多其他电平分量的视频信号中区分出来，需要仔细设计同步信号处理电路。
- Depending on the performance characteristics of the DC restoration circuitry within the video processing channel, some or all of the sync pulse may not be removed from the green channel. 根据视频处理通道中的直流电平恢复电路的性能，部分或全部的同步脉冲不会从绿色通道中移除。
- Oppa is a very honest person and he was going to tell the press that we are pregnant, however, with all the negativity going on (in the press), I asked him not to say anything about the pregnancy. 哥哥是一个非常诚实的人，他准备向媒体公布我怀孕了。但是，各种负面报道出现在媒体上，我要求他不要对媒体说任何有关怀孕的事情。
- The clerk marked up his daybook before going home. 办事员在回家前记好当天的日记帐。
- The answer to my request was in the negative. 对我的请求的答复是否定的。
- I took Mary to lunch she insisted on going Dutch. 我带玛丽出去吃午饭，但她坚持要平摊费用。
- How am I going to get out of this jam? 我怎样才能摆脱困境呢？
- He is going to go out and raise hob. 他今晚要出去纵情狂欢了。
- His answer to my request was a negative. 我的请求遭到了他的拒绝。
- I'm going to make sure if I'm going to Macao. 我要拿定主意我是否去澳门。
- The tests for hepatitis were negative. 肝炎检查结果是阴性。
