文摘

The signal at the output of DDS is non-periodic with variable amplitude and period. The spectrum of the output signal contains harmonic components with non-multiple frequencies. Instability of amplitude and period depends on a specified period. In all cases, the required sampling frequency is greater than the Nyquist frequency. Sampling frequency is determined depending on a specified error of amplitude, error of period, or total harmonic distortion.
