Abstract :
In the digital signal processing, the NCO (Numerically Controlled Oscillators) has a wide range of applications. In this paper, we have researched and implemented the NCO based on the lookup table algorithm with the VHDL and the ISE tool of Xilinx Inc. Finally, the simulation results indicate that the designed NCO is suitable.
