Abstract
PURPOSE:To make it possible to select the characteristics optionally by separating the digital signal to lower digit, and adding the lower digit signal which has been converted to analog to the step voltage which has been generated by the upper digit signal. CONSTITUTION:The digital signal input 1 is separated 2 to the lower and upper digit information 3 and 4, the information 3 is transmitted to the gain control circuit 6 after A/D conversion 5, and is controlled 6 to the gain following the information 4. Subsequently, the information 4 is provided to the level shift amount control circuit 7, too, when the section #1 and #2... are changed, the step voltage which is equal to voltage of the right end of the previous section is generated, and the aforesaid step voltage is maintained in the next section (c). Accordingly, the continuous voltage (d) can be obtained by adding output of the circuit 6 and that of the circuit 7.
