Based on field programmable gates array(FPGA),a method of implementing a long-range agreement transparent,highspeed LVDS and optical communication was firstly introduced.

Using LVDS(low voltage differential signaling)protocol, the link-port transforms the 64 b*30 MHz data stream from DSP into (4 (b*)) 600 MHz data stream, which is connected to other link-ports on different boards.

This paper lays particular stress on new video chips for airborne application, mainly on PAL video and LVDS bus design.

Through size-research of the colour difference signals in colour TV-test illustrating picture, the phase and module of colour difference signals call be obtained simutaniously.

Analysis of differential pressure signal based on wavelet transform and higher-order statistics;

EMD is applied to the differential pressure signal of two-phase flow to obtain frequency components with different scales, and the normalized energy of the component is extracted as the feature of flow pattern identification.

Because the differential pressure signal of oil-gas two-phase flow was a typical non-stationary and multi-component signal,EMD was first applied to break up it into Intrinsic Mode Functions(IMFs) which can be divided into three frequency bands such as high-band(30~50 Hz),mid-band(5~30Hz) and low-band(0~5 Hz).
