This paper investigates the behavior of central Jacobi differentiator in robot identification applications. Jacobi differentiator is a Jacobi orthogonal based algebraic differentiator. It is applied to compute acceleration from noisy position measurements. Moreover, its frequency domain property is analyzed via a finite impulse response (FIR) filter point of view, indicating clearly the differentiators...
In process of real time acquisition and transmission, the spectral signal obtained by miniature spectrometer may contain noise signals superposed on it. But the traditional denoising methods can't achieve the expected performance because of their limitations. A de-noising method for spectral signal in miniature spectrometer based on Stationary Wavelet Transform (SWT) is proposed. We compared the performance...
