专利汇可以提供Adaptive filter专利检索,专利查询,专利分析的服务。并且PURPOSE: To reduce the complication of a circuit and to eliminate an unnecessary delay time by composing a filter of multilayer perceptron, and providing a weight coefficient control circuit to an weight coefficient, simultaneously, a switch to connect and disconnect a path, which connects respective nodes, and a control circuit to control a training cycle from an external part in the path.
CONSTITUTION: A learning controller 48 outputs an weight control signal 49 and an weight coefficient/switch control signal 50 to an weight coefficient switch 20 and weight circuits 36-40 for controlling the quantity of weight and an input signal. These signals respectively go to be the control signals of weight circuits 36-40 and of weight coefficient switch 20. These control signals control the increase and decrease of the quantity of the weight according to the learning rule of the multilayer perceptron so that a final filter output 47 can be a desired value. Then, the control of a changeover switch in the internal part of the weighting coefficient switch 20 and the control of a threshold level is executed by these control signals.
