Abstract

This paper presents performance of NCO used in Digital Down Converter. Digital Down converter consists of NCO and CIC filter as key components; here the output of the CIC filter is the down sampled version of the input signal. As the sampling frequency at the initial stage is high to reduce the sampling frequency for the further processing, CIC filter is used. The NCO is an implementation of a direct digital frequency synthesizer (DDS) which produces a signal at the output with a specified frequency and phase (adjustable at run time).
