数字Dithering的FPGA实现

The FPGA Implementation of Digital Dithering

Dithering是抑制模数转换器ADC量化噪声的重要方法,从数字Dithering量化定理出发,实现了数字Dithering的FPGA过程,对关键设计点给出了详尽的阐述,仿真结果也论证了Dithering对ADC性能的提升有积极的作用,为Dithering算法在实际的应用中起到一定的参考和借鉴作用。

Dithering is an important method to restrain quantization noise of the analog-to-digital converter ADC,from the digital Dithering quantization theorem,the process of FPGA about digital Dithering in ADC is realized,and a detailed description about the key design point is given.Then the simulation results also demonstrate that Dithering has a positive effect to the performance of the ADC,which provides some certain reference and mirror value for the Dithering algorithm in actual application.
