Abstract: For any linear and time-invariant system, its output is the linear convolution between the variable input sequence and the constant system impulse response. When the input is long and the ...
Abstract: The periodic pulse features induced by early damage to rolling bearings under a strong noise background are weak, and the signal decomposition method based on the symplectic geometry ...
This article presents two important DSP techniques, the overlap-add method, and FFT convolution. The overlap-add method is used to break long signals into smaller segments for easier processing. FFT ...
