ABSTRACT:
First and second comparator groups compare first and second analogue signals applied thereto, respectively, with reference voltages and convert the results of the comparison to binary signals to output the binary signals to an encoding circuit. The encoding circuit converts the binary signals supplied from the first and second comparator groups to digital data of a binary code corresponding to the product of the first and second analogue signals to output the digital data.
