METHOD AND DEVICE FOR SIGNAL PROCESSING

PURPOSE:To obtain method and device for signal processing which realize universal numeral calculation without programming by automatically structuring a function which mostly approximates input/output relation when an unknown function is identified. CONSTITUTION:One or two or more kinds of function arithmetic operations are performed on an input signal at a function arithmetic part 1 in parallel, and a weighing coefficient group 2 defined in advance is multiplied by each computed result correspondingly at a multiplication/addition processing part 6, respectively, and an operation to add all the computed results is repeated at a coefficient update part 4 as updating the weighing coefficient group 2, thereby, the optimum computed result for the input signal can be obtained.
