PROBLEM TO BE SOLVED: To solve the problem, with the high-frequencies of a crystal oscillator, an optimum design range which averts spurious oscillations becoming narrowed, so that design becomes very difficult. ;SOLUTION: An area of points, representing main oscillation and spurious oscillations of a conventional mode chart is plotted by a value, in proportion to the total charge volume included in each oscillation, and a region which averts the spurious oscillation of a large area is selected as optimum design region.;COPYRIGHT: (C)2003,JPO
