双调制 meaning in Chinese
[讯] double modulation; dual modulation
Examples
- Design of a dual modem and its dsp realization
5402实现的双调制解调系统 - The technique of pwm wave double modulation is reasonable in theory . beacuase of the great amount of system task and the high requirement of realtime performance , there are few systems were realized by now , applying this arithmetic
软件pwm波双调制这种方法在理论上是可行的,但目前这种成型的系统不多,究其原因是系统任务量大,实时性要求高。 - High resolution digital smps becomes the hotspot in the power supply field . more and more attention has beed payed to how to realize high resolution digital smps , and it has already taken a long step develop . improving the resolution of digital smps by new techniques becomes a forever topic . under the learning of the status and develping trend of smps , considering the practical requirement of task , a control system of smps implemented by microcontroller with high resolution , high speed , high integration is carried out . by combining the embedded system and power electronics , it is discussed that a high resolution smps ’ s output voltage with 0 . 01 % resolution pwm wave output , in the basis of microcontroller , and the pwm wave double modulation arithmetic
