PURPOSE:To obtain a desired multiplied wave output and to require no filter for removing an unnecessary frequency component by generating a power multiplying wave string for sequentially increasing a power multiplier for every square from a fundamental wave input, weighting so as to erase a low order power multiplying wave and synthesizing respective power multiplying wave output. CONSTITUTION:A power multiplying wave generating circuit 1, a coefficient circuit 2 and an adder circuit 3 are provided. The power multiplying wave generating circuit 1 executes the operation of a power multiplying with respect to the fundamental wave input. A maximum order is 2n or 2n-1. It respectively generates the power multiplying waves of the multiplier to be increased sequentially for every square. The coefficient circuit 2 weights respectively to the respective power multiplying wave outputs of the power multiplying wave generating circuit 1 to generate an output. The adder circuit 3 synthesizes the respective outputs of the coefficient circuit 2 to generate the output. Thereby, 2n or 2n-$1 multiplied wave as a synthesized output is obtained and a band-pass filter for removing the unnecessary wave component is not required to an output side.
