By injecting t he comp en2 sation cur rent int o t he p assive loop f ilte r during t he delay time of t he p hase f requency detect or ( PFD) , a maximum reduction of t he p hase noise by about 16dB can be achieved. ...

This document describes how to switch to and program the unisersal serial bus (USB) analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example assembly programs for programming and switching to and from the APLL are also provided in the attached zip file. It is assumed that the reade ...

以传统的C/SDK 撰写Windows 程序，最大的好处是可以清楚看见整个程序的来龙去脉 和消息动向，然而这些重要的动线在MFC 应用程序中却隐晦不明，因为它们被Application Framework 包起来了。这一章主要目的除了解释MFC 应用程序的长像，也要从MFC 源代 码中检验出一个Windows 程序原本该有的程序进入点（WinMain）、视窗类别 ...

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC se ...
