脉冲抖动 [
mài chōng dǒu dòng]
[电子] pulse jitter
- 通过锁相环路的应用可减小延时后的脉冲抖动并得到准确的延时时间。
The delayed pulse jitter is reduced and the exact delay time is obtained by using the PLL. - 硬件上,测速时采用了脉冲去抖动电路,用8253构成PWM调制器。
In hardware, pulse jitter suppression circuit is applied during velocity measuring, The core of PWM modulator is 8253. - 实验证明,该定时器具有输出脉冲抖动小,脉冲宽度和延时控制精确,集成度高,可靠性好的优点。
It has been proven that this radar timer has the merits of little pulse jitter, flexibility, integration and reliability.
