sdr.DDS(K0: float = 1.0, increment: float = 0.0, offset: float = 0.0) Creates a direct digital synthesizer (DDS). Parameters:¶ K0: float = 1.0¶The NCO gain. increment: float = 0.0¶The constant accumulation of the NCO in radians/sample. offset: float = 0.0¶The absolute offset of the NCO in radians. Examples¶ See the Phase-locked loops example.
