ABSTRACT:
Radio equipment for communicating digital data includes a clock modulation part for angular-modulation of a clock signal by a given modulation signal; and a data processing part processing the digital data based on the clock signal angular-modulated in the clock modulation part and producing angular-modulated digital data. In the radio equipment, levels of harmonics generated from the clock signal and the digital data are reducible.
