ABSTRACT:
A first digital signal of a serial form is processed into a second digital signal of a serial form. The second digital signal represents an absolute value of a value represented by the first digital signal. A third digital signal of a serial form is processed into a fourth digital signal of a serial form. The fourth digital signal represents an absolute value of a value represented by the third digital signal. The values represented by the first and third digital signals are compared to generate a comparison-result digital signal representing a result of the comparison. A calculation-result digital signal of a serial form is generated in response to the second digital signal, the fourth digital signal, and the comparison-result digital signal. The calculation-result digital signal represents a value which is approximate to a square root of a sum of a square of the value represented by the first digital signal and a square of the value represented by the third digital signal.
