only by a digital circuit by a method wherein outputs of delay means in the number of (n) which delay an input pulse by a prescribed amount respectively are held in an output state at the time of a fall of the input pulse and the pulse width is measured from the output state held....
A modified algorithm of pulse-width-modulation (PWM) inverter deadbeat control suitable for uninterruptible-power-supply (UPS) systems is presented. Two state variables are measured at each sampling interval, then, using the data, the pulse width is computed in real time in order to force the ...
PURPOSE:To omit counting operation which is not necessary for pulse width measurement and to save electric power by measuring the time difference between a minimum time on which pulse width to be measured is based and the pulse width to be measured. CONSTITUTION:A counter controller 25 switches ...
Mechanism of pulse-width effects on electronic components is described.The relationship of pulse-width and radiation response is presented.Five types of devices are tested under three different pulse-widths(about 20 ns,50 ns,150 ns) of different simulative radiation sources,the dose rate is about...
Pulse widths and flux densities are measured. The frequency dependence of the profile shape and the pulse width is discussed. Our data base has been combined with other published data to generate flux spectra between 1.4 GHz and 5 GHz. The mean flux spectral index has a value -1.9. Our ...
To get a pulse, I put my finger in a bullet hole. 我把手指摁在子弹孔上,还有一丝脉搏的迹象. 期刊摘选 By increasing the input energy, the wider tuning range of pulse width could be achieved. 增大抽运能量, 脉宽可调范围也相应地增大. 期刊摘选 This radar is operated by an electronic pulse....
In the PIM scheme, the time interval between every two consecutive pulses (of the same pulse width) conveys the data being transmitted. This is while in PIWM, pulse widths are also used to carry some additional data. To conclude, a major advantage of anisochronous modulation schemes over ...
Computer-aided analysis has made some achievements in pulse diagnosis, especially in pulse-wave-pattern classification (PWPC). For example, Wang et al. divided 407 sets of pulse data into five pulse patterns by using a Bayesian network based on six pulse parameters: depth, width, length, ...
A pulse of width T is divided into N subpulses of width τ, where N = T/τ. The phase of each subpulse is either 0 or π radians, chosen at random or pseudorandom. N, the number of subpulses. Approximately 0.5/N (in the best of cases) Sidelobes are not low, especially with ...
pulse width is given in the figure as 1 microsecond (10−6second). It should be noted that the pulse is shown as containing only a few cycles of the sine wave; however, in a radar system having thevaluesindicated, there would be 1,000 cycles within the pulse. In the figure the ...
