Numerically Controlled Oscillator employing a reduced size lookup table and a corresponding method |
摘要 |
<p>A system and method for reducing the computational complexity of the calculations performed by a Numerically Controlled Oscillator (NCO). Through exploitation of mathematical symmetries and other techniques, the size of a lookup table of sinusoidal values employed by the NCO to approximate sinusoids may be reduced by the combination of different frequency shifts.</p> |
