摘要： PURPOSE:To obtain the same modulated wave signal at only one adjustment even with different characteristics, by making a DC voltage superimposed on a sound source signal coincident with a peak value of a moldulation signal and changing a resistance value of a field effect transistor depending on the difference between both voltages. CONSTITUTION:In Figure, an FET3 is used at the ohmic region, the gate-to- source voltage VGS is changed (decreased) depending on the modulation signal level change (e.g., increased) from the signal source 5, a drain-to-source resistance RDS is changed (decreased) accordingly, the amplification factor A of an inverting amplifier circuit is changed (increased), and a modulated wave signal in which the sound source signal (carrier) from the signal source 1 is amplitude- modulated with a moldulation wave signal from the signal source 5 is picked up from an output terminal 7. The VSG of the FET3 is OV when the voltage of the modulation wave signal is maximum independently of the position of the slider of a potentiometer VR2, and the maximum of the VGS is gradually reduced as the slider position is moved from the terminal VR2b to the terminal VR2a.
