| Abstract: | Based on the concept of incremental computations, a digital oscillator structure is proposed which consists of two incremental integrators and one incremental multiplier. Models for these elements are developed and detailed analyses are made showing that the errors of the proposed structure are extremely low compared with the direct-form one. The proposed oscillator structure can be implemented without a hardware multiplier and can generate sinusoidal waveforms in the differential pulse code modulation representation. |
