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 ...
VHDL/FPGA/Verilog The Hilbert Transform is an important component in communication systems, e.g. for single sideband m
The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the n ...

What happens with your machine when you need to move away from the computer for 10 or more minutes? How secure is your data? Can someone sit on your chair while you are at a coworkers office and play with your data?
Maybe you need a computer locking tool that is small and easy to use yet powerful ...

技术资料 PLL锁相环
PLL(Phase Locked Loop)： 为锁相回路或锁相环，用来统一整合时钟信号，使高频器件正常工作，如内存的存取资料等。PLL用于振荡器中的反馈技术。 许多电子设备要正常工作，通常需要外部的输入信号与内部的振荡信号同步。一般的晶振由于工艺与成本原因，做不到很高的频率，而在需要高频应用时，由相应的器件VCO，实现转成高频 ...

技术资料 基于滑模观测器与分数阶锁相环的无传感器PMSM矢量控制
Abstract: A sliding mode observer and fractional-order phase-locked loop (FO-PLL) method is proposed for the sensorless speed control of a permanent magnet synchronous motor (PMSM).The saturation function is adopted in order to reduce the chattering phenomenon caused by the sliding mode observer. In ...
