PURPOSE:To generate an optional waveform having a specific period and a specific voltage level by passing an optional level voltage generated from a voltage source through a switch means switched by a signal of a specific period from a signal source. CONSTITUTION:An analog switch 26A and an analog switch 26B are provided corresponding respectively to a positive voltage level set by a positive voltage source 6A of a variable voltage source circuit 6 at a level set terminal 28A and to a negative voltage level set by a negative voltage source 6B of the variable voltage source circuit 6 at a level set terminal 28B. Since the analog switches 26A, 26B repeat switching in response to the signal period from a signal generator 2, a waveform having a signal period from the signal generator 2 in response to the switching and having upper or lower limit levels set by the variable voltage source circuit 6 is outputted from a waveform output terminal 30. |
