Introduces the digital electro-hydraulic proportional control amplifier which is designed by DSP technology and based on PROFIBUS-DP,including the construction of hardware and the composition of software.
In order to realize digitization and intellectuality of the servo valve based on NdFeB permanent magnetism, the digital servo controller has been developed, which realizes transmission and communication of the digitized signals of the servo valve through Profibus on-the-spot bus technology and industrial Ethernet. Using Visual C++ 6.0 language combined
Such systems play an important role in time-frequency analysis and digital signal processing.
There are many advantages in the use of Hadamard matrices in digital signal
An Inhomogeneous Uncertainty Principle for Digital Low-Pass Filters
This article introduces an inhomogeneous uncertainty principle for digital lowpass filters.
The measure for uncertainty is a product of two factors evaluating the frequency selectivity in comparison with the ideal filter and the effective length of the filter in the digital domain, respectively.
