DIRECT DIGITAL SYNTHESIZER, DIRECT DIGITAL SYNTHESIZER FOR TRANSMISSION AND DETECTION, AND MRI APPARATUS

摘要

The present invention is transmitted and for outputting the amplitude data detected at a high clock frequency than the clock frequency of the phase data relates to a direct digital synthesizer for, the synthesizer includes a first phase with the transmitted data to output a first phase in the clock frequency, the first clock frequency Roda small second phase data to output a second clock frequency, and the loss in reduction treatment cut and outputting the additional data to compensate for the phase information unit (5) and, interpolation unit to perform the interpolation process in the second phase data to output a third phase data in the third clock frequency greater than the first frequency (6) and, includes a detector for outputting the amplitude data type according to the third phase data. The detected signal amplitude data may be output to a high third clock frequency than the second clock frequency of the data to be transmitted a second phase.
