Abstract
PURPOSE:To make the frequency of a necessary sampling clock into fs with respective D/A converters by providing N pieces of D/A converters in parallel to input data in which the data are inserted and a repetitive frequency is made into Nfs. CONSTITUTION:The digital data of a sample frequency fs through an input terminal 10 are made into the data DA of a sampling frequency 2fs with a digital filter 11, a switching circuit 12 is switched by a switching control signal SW from a timing signal forming circuit 15, odd numbered data DA0 are supplied to a D/A converter 13, even numbered data DAE are supplied to a D/A converter 14, and converted to the analog data by sampling clock pulses SP0 and SPE from the circuit 15. The folding of a frequency fs/2 or above removed, synthesized alternately from a switching circuit 17 and not needed by a low pass filter 18 is removed. Thus, the sampling clock frequency of respective D/A converting parts may be the fs.
