Coherence detector with$A of a variety of n signal inputs (EST darr;i darr; (1 = i = n);E1, E2, E3, E4at which a respective input signal value is present, $ A of a first sorting device (S1) for sorting the n input signal values (E1, ...,E4) according to their value (A, B, C, D) and to the parallel output of the n sorted values, $A of a variety of n-1 subtraction devices ("-) for the subtraction of two adjacent sorted values ((D-C);(C-B)(B-A),$A of a second sorting plant (S2) to sort the n-1 differences received ((D-C),(C-B)(B-A)) as regards its amount and the issue of the smallest difference (" "),$A of a selection body ("=";MUX1,the smallest difference (" ") that gives the input signal values to this associated pair of values, and an output device (" Sigma;/2");which adds the issued value pair and issues its mean value (KE).
