WebDecimation, or Interpolation, is the averaging method, which combined with oversampling, which increases the resolution. Digital signal processing that oversamples and lowpass-filters a signal is often referred to as interpolation. In this sense, interpolation is used to produce new samples as a result of ‘averaging’ a larger amount of samples. Webfactor R (expansion from the origin of the frequency axis). Fs’−periodic replications of the expanded spectrum are maintained, as usually for digital signals. Figures 2 and 3 represent what happens when decimation factor is R=2, for a low−pass and a high−pass spectrum, respectively, using normalized frequency axis (f 2 f/Fs or /Fs using gratuity reporting

WebSep 26, 2024 · 1 Answer Sorted by: 0 There are several methods of interpolation that can be used to upscale the decimated image back to its original size. One method is the nearest neighbour method (pixel replication). Some other methods include: • Bilinear interpolation → less jaggies/staircasing • Bicubic interpolation → less jaggies/staircasing WebNow, let's look at the fact that you're decimating by a factor of 2: That means that you throw away every other output sample.
