APPRATUS AND METHOD FOR FREQUENCY SYNTHESIS REDUCING NOISE

摘要

An embodiment of the present invention relates to an apparatus and a method for synthesizing a frequency. According to an embodiment of the present invention, the frequency synthesizing apparatus is an apparatus for synthesizing a frequency in which a frequency synthesizer includes a digital analog converter. The frequency synthesizer outputs synthesized data by synthesizing first sine wave formation data according to an inputted generation frequency, and second sine wave formation data to suppress a noise generated in the digital analog converter, to output the synthesized data. The digital analog converter converts the outputted synthesized data into an analog signal. With the frequency synthesizing apparatus according to an embodiment of the present, the noise caused by the digital analog converter can be effectively removed.
