Abstract (en)
[origin: WO2020094506A1] Interpolator for interpolating, by a ratio n, the sampling frequency of a signal, called the input signal, the interpolator being characterised in that it comprises: - a first interpolation stage (101) comprising an over-sampler configured to over-sample the input signal by a ratio n 1, with n 1 being a sub-multiple of n, and a filter for filtering the over-sampled signal; and - a second interpolation stage (102) comprising a linear interpolator configured to interpolate, by a ratio n 2, the signal originating from the first interpolation stage, with n 2 being a sub-multiple of n; and - a third interpolation stage (103) comprising a blocking interpolator configured to interpolate, by a ratio n 3, the signal originating from the second interpolation stage, with n 3 being a sub-multiple of n. Associated interpolation method and method for dimensioning a high-order interpolator.
