PURPOSE:To extend the dynamic range, by giving the positive DC bias voltage more than the negative amplitude of the input signal voltage, through the potential determined with the two resistors after the input signal is passed through the capacitor. CONSTITUTION:The sinusoidal signal taking the zero potential fed to the signal input terminal 18 as the center is passed through the capacitor 10, then it is passed through the resistors 11 and 12 of the same resistance value, and the input signal is swung by taking a half of the power supply voltage as the center. Further, the dynamic range can be extended by giving the positive DC bias voltage more than the negative width of the input signal voltage. |
