Abstract

PURPOSE:To obtain stable signal level, by connecting an output line of a logical circuit, external power supply and a diode, and fixing a positive side voltage of rectangular wave output to a predetermined value. CONSTITUTION:A diode 11 and voltage dividing resistors 12, 13 are provided between a digital logical circuit 2 and a low-pass filter 3. Although the positive side voltage of the logical circuit 2 is fluctuated due to dispersion of elements, the positive voltage of an input signal to the filter 3 is fixed to voltage dividing voltage of resistors 12, 13. Thus, a sinusoidal wave signal not affected with fluctuation of the output amplitude of the logical circuit 2 can be obtained at the output of the filter 3.
