Abstract

PURPOSE:To achieve a signal synthesizer with small loss, by providing a switch circuit which is in on/off control in sampling frequency, and a resonant transfer circuit for input and output side. CONSTITUTION:Input side of resonant transfer circuits 24-26 is connected respectively to signal input terminals 21-23, and output side is connected to switch circuits 27-29. The output side of the switch circuits 27-29 is connected to a resonant transfer circuit 35 through a signal summing point 34 and an output terminal 36 is led out from a circuit 35. A control signal in which frequencies more than double the minimum continuous frequency band including all the bands of a signal wave group to be synthesized and it is not overlapped in timing at the time point in zero crossing of the terminal voltage of an input side capaditance of the circuit 35, is applied to control input terminals 31-33 of the switch circuits 27-29, to make on/off control of the switch circuits 27-29.
