An efficient low-frequency digital sinusoidal oscillator is proposed and its performance is evaluated. The proposed oscillator structure can generate sinusoidal signals with a large number of samples per cycle without the need to increase the width of the multiplier coefficient. The proposed oscillator utilizes two multiple-output direct-form digital oscillators with two different multiplier coefficients. The simulation results show that the total harmonic distortion of the generated sinusoid can significantly be improved using a low-pass filter.
