例句與造句

1. In signal processing circuits, use of a chopper stabilizes a system against drift of electronic components; the original signal can be recovered after amplification or other processing by a synchronous demodulator that essentially un-does the " chopping " process.
2. So to extract U, a synchronous demodulator is utilized, which uses the subcarrier to briefly gate ( sample ) the chroma every 280 nanoseconds, so that the output is only a train of discrete pulses, each having an amplitude that is the same as the original U signal at the corresponding time.
3. It's difficult to find synchronous demodulator in a sentence. 用synchronous demodulator造句挺難的
