Abstract: |
||||
Numerically Controlled Oscillator (NCO) is an important component in many Digital Communication Systems such as Digital Radio and Modems, Software Defined Radios, Digital Down/Up converters for Cellular and PCS base stations etc. This work presents a technique for the generation of analog sinusoidal signals with high spectra quality and reduced circuitry resources. A common method for digitally Generating a complex or real valued sinusoid employs a Look-Up table based scheme. NCO is a new technology of Frequency synthesis; It is developed the using third generation of Frequency synthesis technology. The technique of NCO is gaining popularity as a method of generating Sinusoidal signals and modulated signals in digital systems. The test Results are matching with theoretical and simulated results. Numerically Controlled Oscillator (NCO) is an important component in many Digital Communication Systems such as Digital Radio and Modems, Software Defined Radios, Digital Down/Up converters for Cellular and PCS base stations etc. The NCO Design is first simulated and optimized on the software tool MICROWIND 3.5 using a standard 45 nm technology. |
