An apparatus for reducing errors in the digital measurement of a desired characteristic of a periodic analogue signal inlcudes: a sampling facility for sampling the analogue signal over one or more periods of a signal to obtain a set of under-read samples during a first half period, each under-read sample having a corresponding under-read error, and a set of over-read samples during a second half period each over-read sample having a corresponding over-read error; and a processor for selecting the number of samples in the sample sets for each half period to be sufficient to allow the over-read errors to offset the under-read errors, to a desired extent, in a calculation of the desired characteristic of the analogue signal. |
