Apparatus for determing the optimal value of a control parameter and use of the apparatus.

摘要

An apparatus for rapidly determining a control parameter t = t0 at which the sum S of n functions Fi (i=1,..,n) reaches a minimum, a maximum, or a given value, wherein each function Fi(t) changes its first derivative only at given discrete values tij of the control parameter t is described, comprising a random access memory (RAM) addressed by said values tij, means (3) for summing the second derivatives of said functions, a circuit (4-10) to perform a double integration to evaluate S, and a comparator (11,12) to determine the optimum control value; also disclosed is a new gate array (GA) which rapidly reproduces the addresses used to address the RAM, while skipping all others. This gate array is advantageously used as a part of the apparatus for determining a control parameter. Further, the use of the devices in a communication network is described. <IMAGE>
