| Abstract(in English) | An arbitrary directivity forming method by two microphones using a circuit structure consiting of multiple directivity forming circuits is proposed. Because just one zero is adjustable in each directivity forming circuit, it is important to decide a guideline for assigning multiple zeros so as to minimize a design error. In this paper, the guideline is formulated as a design error adjustment problem by introducing a specified error constraint in the approximation range and solved by PSO. |
