Optional high speed pulse modulation capability 任意高速脈沖調(diào)制能力
General specification for pulse modulation tubes 脈沖調(diào)制管總規(guī)范
This type also can be called pulse modulation laser diode module 可調(diào)制式激光器也就是脈沖式激光器。
4 . we have found and analyzed the phenomenon of pulse modulation and autoecious pulse ( 5 )針對實驗中發(fā)現(xiàn)的脈沖序列調(diào)制、尾脈沖等現(xiàn)象進(jìn)行了分析與討論。
It is detailed to analyze two kinds of control strategy , - spwm and hcpm ( hysteresis controlled pulse modulation ) 本文詳細(xì)分析兩種控制策略? spwm控制和滯環(huán)控制。
The method can measure the following parameters , ( pulse attitude ) pa , ( pulse width ) pw , ( time of approach ) toa , snr , ( radio frequency ) rf , pulse envelope characteristic parameters and intra - pulse modulation parameters with a high precision and a high discrimination 該算法能夠分析雷達(dá)信號的脈沖脈幅、脈寬、到達(dá)時間、信噪比、載頻、脈沖包絡(luò)特征參數(shù)和脈內(nèi)調(diào)制特征參數(shù)。
A circuit topology of the inverter with duty cycle extended active clamp forward style high frequency pulse dc link is adopted by each independent inverter . each inverter is cascaded by a circuit with duty cycle extended active clamp forward style high frequency pulse dc link and a dc / ac inverting bridge . the control strategy of voltage mode pwm forwardback is adopted by the former , and the control strategy of three - state discrete pulse modulation ( dpm ) hystersis current is adopted by the later 每個獨立的航空靜止變流器采用占空比擴(kuò)展有源箝位正激式高頻脈沖直流環(huán)節(jié)電路拓?fù)?,由占空比擴(kuò)展有源箝位正激式高頻脈沖直流環(huán)節(jié)電路與dc ac逆變橋級聯(lián)而成,前級采用電壓型pwm前饋控制技術(shù),后級采用三態(tài)dpm電流滯環(huán)控制技術(shù)。
