PhaseLockedLoop
％The phase locked loop(PLL),adjusts the phase of a local oscillator
％w.r.t the incoming modulated signal.In this way,the phase of the
％incoming signal is locked and the signal is demodulated.This scheme
％is used in PM and FM as well.
％We will implement it by using a closed loop system.Control systems
％techniques are applied here.( The phase locked loop (PLL), adjusts the phase of a local oscillator wrt the incoming modulated signal.In this way, the phase of the incoming signal is locked and the signal is demodulated.This scheme is used in PM and FM as well.

USB通信编程，获取USB设备信息，如果编译不通过，你需要下载NTDDK中的hidsdi.h 和 hid.lib文件等。(USB communication programming，get the USB devices informateion ,if there have link errors,you have to download the header files hidsdi. H, the library file hid. Lib,etc in the NTDDK.)
