Modulation Domain and Pulse Analyzer(MDPA) analyzes signal using a plane domain which is consisted of frequency and time.

调制域及脉冲分析仪利用时间和频率构成的平面域对信号进行分析。

It also includes, Hall element inputs, a sequencer for commutation control, fixed off time pulse width modulation (PWM) current control and locked rotor protection.

它还包括霍尔元件输入、整流控制定序器、固定停机时间脉冲宽度调制(PWM)电流控制以及锁定转子保护。

The laser pulse modulation system has been used in a picosecond time-correlated single photon counting spectrometer with perfect effect.

该激光脉冲调制系统已经应用在皮秒时间相关单光子计数光谱仪系统中，取得了比较理想的效果。

Shannon would also contribute to the further development of pulse-code modulation (along with Bell alumni Bernard M Oliver and John R Pierce) at around the same time, using technology that eliminated some of the issues (such as complex circuitry) from the earlier, but conceptually similar, implementation from Briton Alec Reeves in 1938.
