％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

Pipeline synchronization is a simple, low-cost, highbandwidth,highreliability solution to interfaces between synchronous and asynchronous systems, or between
synchronous systems operating from different clocks.
This paper presents several low-latency mixed-timing
FIFO (first-in–first-out) interfaces designs that interface systems
on a chip working at different speeds. The connected systems
can be either synchronous or asynchronous. The designs are then
adapted to work between systems with very long interconnect
delays, by migrating a single-clock solution by Carloni et al.
(1999, 2000, and 2001) (for “latency-insensitive” protocols) to
mixed-timing domains. The new designs can be made arbitrarily
robust with regard to metastability and interface operating speeds.
Initial simulations for both latency and throughput are promising.

Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become
the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM
jamming is analyzed by time domain autocorrelation method in this paper．It’S jamm g peculiarity and幾out—
putting signal’S jamming peculiarity ale explained．At last，these time series models ofnoise FM jalllIIling sig—
nal and幾outputting signal ale built．
