A 13-bit resolution ROM-less direct digital frequency synthesizer based on a trigonometric quadruple angle formula.

A ROM-less direct digital frequency synthesizer employing trigonometric quadruple angle formula is present in this paper. The worse case spectral purity is better than -130 dBc. The amplitude resolution is up to 13 bits, while the phase resolution is 12 bits. Neither any scaling table nor error corr...
