Abstract
A method of filtering a signal sampled by a sampler, for example, in an equivalent time oscilloscope includes applying a correction to an actual frequency response of the sampler, with respect to a reference frequency response, to a first frequency range of the sampled signal, and transitioning across a second frequency range of the sampled signal from the correction applied to the first frequency range to no correction of the actual frequency response of the sampler, the second frequency range being higher than the first frequency range. The method further includes compensating in a third frequency range of the sampled signal for excess gain incurred while applying the correction and transitioning from the correction to no correction in the first and second frequency ranges, respectively, so that statistics of asynchronous components of the sampled signal are preserved, the third frequency range being higher than the second frequency range.
