We describe a new method of frequency-domain deconvolution when the kernel has no spectral inverse. Discrete frequency interpolation is used to aviod zero-valued frequency samples. The algorithm does not suuer from the spectral singularities of the original kernel, its complexity is proportional to the fast Fourier transform, and a comparative noise study(More)
This paper describes an on-line computer supported tactile sensor that can recognize complex industrial objects, identify a seam location, and track a three-dimensional seam trajectory for an arc welding robot. A one finger tactile sensor with two degrees of freedom is used. The supporting microcomputer system organizes and reduces the useful sensor data(More)
We studied application of the cepstral analyses to the real-time signal processing. The paper describes the utilization and scope of the signal exponential weighting, diierent approaches to the phase unwrapping, and their computational complexity. A new unwrapping method that reduces the cepstral aliasing by combining the real and the diierential cepstrum(More)
