For the multisensor systems with complex colored noise, using the modern time series analysis, a steady-state optimal and self-tuning Kalman filter weighted by scalars is presented. State augmentation and measurement transformation methods are applied to transform the colored process noise and colored observation noises into white noises. So these problems are transformed to Kalman prediction problems...
A pulsed method for impedance spectroscopy measurement, different from the traditional swept frequency methods, is presented. A string of square-wave pulses is digitally generated as the excitation signal to the sensing electrodes. A pulsed measurement system is described. A sample-collecting method for sampling the instantaneous response signals is implemented based on a field programmable gate arrays...
The edge detection for images based on traditional wavelet analysis has the disadvantage of not being sensitive to direction properties, so aimed at the problem the article makes some improvement and puts forward a new kind of wavelet transform used for image edge detection. Compared with the detection based on Canny operator, it can be concluded that the new kind of edge detection based on wavelet...
