Patent ID: 8380453

Claim:
A method for determining an occurrence distribution of a signal level of a measured signal measured respectively in overlapping observation intervals via a time or frequency raster, said method comprising: determining incrementations of a memory cell in a first memory, said memory cell associated with a value of the time or frequency raster and the signal level of the measured signal; determining a number of un-delayed incrementations of every memory cell of the first memory over the number of already measured observation intervals by summing the number of incrementations of every memory cell of the first memory determined in every already measured observation interval, each comprising several measurement cycles; delaying the number of the un-delayed incrementations of every memory cell of the first memory over the number of already measured observation intervals by a delay time corresponding to a number of measurement cycles in the observation interval by a delay unit; and determining the occurrence distribution of the signal level of the measured signal in the observation intervals in the time or frequency raster by subtracting the number of delayed incrementations of every memory cell of the first memory over the number of already measured observation intervals from the number of un-delayed incrementations of every memory cell of the first memory over the number of already measured observation intervals within the raster of the number of measurement cycles.
