Abstract
A high-resolution direct digital synthesizer (DDS) intended for hydrogen masers is designed and constructed. Its phase noise is investigated by simulating its output signal and calculating its phase spectrum, and by measuring its phase spectrum directly. In addition its phase noise is compared with that of other synthesizers used in hydrogen masers
