pulse-width pulse-frequency modulator 调宽调频调制器
pulse width-pulse frequency modulation control 调宽调频控制
pulse width and pulse amplitude 脉冲宽度与脉冲幅度
The front panel controls allow the user to set pulse width and frequency independently, or to set frequency and duty cycle, which then sets the pulse width accordingly.
前面板控制允许用户设置脉冲宽度与频率或先设置频率与占空因数，再设置脉冲宽度。
Pulse width Modulation device is a circuit which can produce square wave signal with fixed period and adjustable pulse duration ratio (pulse width).
脉宽调制器是一种能够产生周期固定而占空比(脉宽)可调的方波信号的电路。
The experimental results show that a bigger diffraction efficiency delay rate can make the establishing time of the laser pulse and the pulse width shorter, and make the peak power higher.
实验结果表明，在一定范围内增大衍射延迟速率可以缩短脉冲建立时间，缩短脉冲宽度，增加峰值功率。
