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.
由於大量的功率被廣播發射機用來發送同步脈衝，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衝從包含著許多其他電平分量的視頻信號中區分出來，需要仔細設計同步信號處理電路。
