Abstract
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 f,>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 (,) with a bandwidth of B′>B, and that a composite signal is tapped off from the output of the low-pass filter (,). 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.
