Abstract

PURPOSE: To extend the dynamic range of an adder, by applying an output of a digital low-pass filter inputting the output of an adder with opposite polarity, to the adder for a differential pulse code modulation signal and an output signal of a forecasting device.
CONSTITUTION: A closed loop is constituted, in which the sum between an input 7 signal from an input terminal 7 and an output of a forecasting device 9 and the difference between the input signal and the output of a digital low-pass filter 14 are obtained at an adder 13 and the output of the adder 13 is inputted to the filter 14 and the device 9. After unnecessary component is rejected by inputting the output of the adder 13 to a low-pass filter 11, the output is outputted to a terminal 12 as an analog output. The DC component produced through the addition of the output of the device 9 and the input signal from the input terminal 7 passes through the lowpass filter 14 and is subtracted at the adder 13 to reject the DC output of the adder 13. Thus, the clipping due to overflow of the adder can be avoided, allowing to extend the dynamic range of the adder substantially.
