<p>PURPOSE:To decrease long-period errors with low cost constitution by providing an element absorbing stationary deviation errors comprising a bias section. CONSTITUTION:A signal 602 subjected to amplitude compression by an amplitude compression section 601 inputted from an input signal terminal 600 is inputted to one input of a 1st comparator section 603, which compares the quantity of two input signals and outputs the result by binarization Its output is given to a temporary storage section 605. An output of the comparison section 603 is held temporarily synchronously with the clock 606 of a prescribed period fed from a control section 690 at the storage section 605, which outputs the result 607. The output 607 is fed to a digital memory section 692 and a 1st integration or an integration simulation section 608, a binary signal is integrated and an integration output 609 is fed to the other input of the comparison section 603. On the other hand, a bias from a bias section 620 is fed to a 1st bias supply section 621, whose output is given to the integration section 608 as a bias. Thus, the stationary deviation errors are absorbed and a long-period errors are reduced as a whole.</p> |
