sync pip的用法和樣例：
例句
- A significant amount of power is used by the broadcast transmitter to send the sync pulse.
由于大量的功率被廣播發(fā)射機用來(lái)發(fā)送同步脈沖，一般將視頻信號的極性設計為在傳送同步信號降低功耗的方式。 - 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.
為了能夠方便的將同步脈沖從包含著(zhù)許多其他電平分量的視頻信號中區分出來(lái)，需要仔細設計同步信號處理電路。
