Abstract
Measurement of the successive levels of a received signal is achieved by combining together the elements of groups of digitized samples (E1 to Em) which are taken from the signal during successive sampling windows (W) positioned by a local clock (H) kept thoroughly synchronous with the signal. The combination consists of a weighted average so as to take account of the transmission conditions: passband of the channel, required flow rate, background noise, etc, likely to distort the signals transmitted and therefore to lead to errors in the measurement of the actual levels thereof. Such weighting is achieved by using the set of digital samples (E1 to Em) corresponding to a single group, for addressing a memory (10) in which the values to be selected for each one of the digital words have been previously stored.
