Web1. The DAC is selected for its resolution, accuracy, and noise performance. The resolution may be dependant on the application, but it is common to see 16-bit or greater resolution in this circuit. Errors in the output of the DAC are considered non-linearity errors. Non-linearity errors are expressed as Webthe non-linearity of the VCO voltage-to-frequency relationship. The reason for this is the very different signal amplitudes that modulate the VCOs. The modulating signals of the VCOs in Fig. 1a correspond with the full scale value of the input signal x(t), what results in a highly non-linear behaviour.
