PROBLEM TO BE SOLVED: To solve such a problem of an FM modulation amplifier that when converting an input signal into a voltage via an FM modulation circuit and an FV conversion circuit, it is impossible to output only the frequency shift of a signal while converting into a voltage, and to convert only the frequency shift of an FM modulation circuit into a voltage from an input signal.SOLUTION: A difference output circuit of a voltage waveform, including a fundamental wave voltage conversion waveform and a shift, outputs an output obtained via an FM modulation circuit and an FV conversion circuit, and an output obtained by passing the output from duplicating fundamental wave oscillation circuit and FV conversion circuit through a reverse phase conversion circuit, while joining. |
