The architecture is based on a 32 bit phase accumulator and a look-up table (LUT)... WebA numerically-controlled oscillator ( NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal. [1] NCOs are often used in conjunction with a digital-to-analog converter (DAC) at the output to create a direct digital synthesizer (DDS). [3] bareburger nutrition menuWebThe NCO generates a sine waveform using the concept of direct digital synthesis. In direct digital synthesis, the samples of the sine wave are stored in memory and are read out to generate the output sine wave. The frequency of the output sine wave is controlled by the clock speed and appropriate skipping of intermediate data points. sustantivo y adjetivo online

"Web$\begingroup$ A DDS usually refers to the combination of an NCO with an ADC, is that the case or are you completely digital within this same FPGA implementation? If that is the case, why would you make another NCO to translate a single IQ complex tone that another NCO is creating instead of just chaning the original NCO directly? " - Dds nco
