Abstract :
In this paper I bring forward a way to design numeric control oscillator (NCO)that can be used in amplitude modulation, frequency modulation, phase modulation and digital up converter(DUC). Emphatically, this paper analyses characteristics of frequency control word (FCW) and propose solution of different application.Finally a FPGA implementation is presented.
