Abstract (en)
[origin: CA2230481A1] A method of forming an aggregation of N > 1 band-limited time signals, each with a bandwidth of ~ B, which are present as analog and/or digital sampling values, with a respective sampling frequency of fA > 2B, is characterized in that the sampling values of all N time signals are offset in time and superimposed on each other, and are jointly input to a low-pass filter (12) with a bandwidth of B' > B, and that a composite signal is tapped off from the output of the low-pass filter (12). This allows the aggregation to be performed in a considerably shorter calculation time, a number of slow and expensive aggregation elements can possibly be saved, and the damping of the signals during processing can be minimized, as well as the corresponding loss of information.
