The electromagnetic compatibility of PCB (printed circuit broads) has become a problem that must be considered by engineers while designing the circuits with the extending of signal frequency. In the paper, we proposed an improved modeling method that use the electric dipoles deduced from the near-field scanning technique in time domain to analyze the characteristic of PCB's electromagnetic compatibility...
For the characteristics of wave-piercing catamaran longitudinal motion when sailing with high speed in random waves, this paper proposes a state estimation algorithm for wave-piercing catamaran longitudinal motion based on EKF. On the one hand noise is filtered out from the noise pollution measurement signal as much as possible, and the desired signal is separated therefrom; on the other hand, all...
This paper presents an effective design of a asynchronous FIFO circuit for multiple asynchronous clocks data transmission. The dual synchronization and gray code are proposed. According to experiments, the probability of metastability is reduced effectively. In the simulation the proposed circuits can operate at a clock rate of 256 MHz while in writing and 329 MHz in reading and is implemented in...
