ABSTRACT:
There is provided an analog-to-digital conversion apparatus that converts analog signals into digital signals. The analog-to-digital conversion apparatus includes: a plurality of analog-to-digital converters that converts analog signals into digital signals in different timing by a predetermined phase; a plurality of data inserting units that is provided corresponding to the plurality of analog-to-digital converters and outputs zero-inserted data that is made by respectively inserting data with data value zero between the digital data output from the respectively corresponding analog-to-digital converters by a predetermined number; a synthesizing unit that respectively synthesizes the zero-inserted data to generate the digital signal; and a plurality of filter units that is provided corresponding to the plurality of analog-to-digital converters, has filter coefficients based on a frequency characteristic of each of the analog-to-digital converters so that the digital signal generated form the synthesizing unit is a digital signal obtained when the frequency characteristics of the plurality of analog-to-digital converters are the same as one another, and passes through the corresponding zero-inserted data to supply the data to the synthesizing unit.
