VARIABLE INTERPOLATOR FOR NON-UNIFORMLY SAMPLED SIGNALS AND METHOD

摘要

variable interpolator 110 is an interpolation factor L for performing an interpolation of the input signal (124) gatneunde, where L is variable and includes a minimum value. Variable interpolator comprises a differentiator (110-1), the chopper 112 and the integrator 110-2. Differentiator 110-1 is to perform an interpolation in response to the differential contribution of the input signal on the differentiator to provide a differentiator result signal 134. Chopper are connected to the differentiator for chopping the differentiator result signal as a function of the minimum value of L, where there is non-uniform at least one sample of a duration that extends beyond the shortest duration and at least one sample of a shortest duration with respect to the interpolator input signal that contains the sampled signal, and the minimum value of L corresponds to the duration of the sample of shortest duration, that the sample interpolator comprises a uniformly sampled signal being one of fixed duration with respect to the input signal, the minimum value of L corresponds to the fixed duration. Integrator integrator portion of the interpolation is carried out, and corresponding to the output 142 of the variable interpolator, responsive to the differentiator result signal that the signal integrator to provide the chopped.
