The input terminal of storage D1, phase register D1 are on the one hand anti-by new phase data generated after upper clock period effects
The input terminal of accumulator is fed to so that accumulator continues to be added with frequency control word Δ θ under the action of following clock, another party
Quantizer Q1 is sent this value as address is searched into face, and the input of degree of precision, larger bit wide is abandoned low ratio by quantizer Q1
After special position, the output of lower accuracy, smaller bit wide is obtained, is directly used as storing the address of sine and cosine data look-up table below,
Look-up table exports corresponding Wave data according to this address.
