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