A novel ROM-less architecture for Direct Digital Frequency Synthesizer based on Linear Neural Networks
G.C. Karthikeyan, K. Lakshmanan, K. Hariharan · 2015
In Conventional Direct Digital Frequency Synthesizer, the presence of ROM results in large size and complexity. Some DDFS is based on a mathematical series which also has some computational time delay. This paper deals with the Artificial Neural Network based DDFS architecture with linear transfer function, unlike the non-linear transfer function [3], which has low complexity, low computational delay and high spectral purity. The proposed DDFS has a high SNR (Signal to Noise Ratio) of about 48dB.
