Downsampling (signal processing) - Wikipedia

WebThe resampled signal starts at the same value as x but is sampled with a spacing of len (x) / num * (spacing of x). Because a Fourier method is used, the signal is assumed to be periodic. Parameters: xarray_like The data to be resampled. numint The number of samples in the resampled signal. tarray_like, optional In digital signal processing, upsampling, expansion, and interpolation are terms associated with the process of resampling in a multi-rate digital signal processing system. Upsampling can be synonymous with expansion, or it can describe an entire process of expansion and filtering (interpolation). When upsampling is performed on a sequence of samples of a signal or other continuous function, it produces an approximation of the sequence that would have been obtain… WebBrowse Encyclopedia.
