WebSep 20, 2024 · A DAC such as the AD9783 made by Analog Devices of Norwood, Mass. can provide adequate performance in the second and third Nyquist zones. Using the DAC to generate the IF in the higher Nyquist zones (e.g., the second and third) may allow for a lower data clock rate between the processing circuitry and the DAC, saving cost and power, at a ... WebFeb 6, 2024 · the amplitudes of images in the first, fourth, fifth Nyquist zones decrease and increase in the second, third, sixth and seventh ones. According to Figures 1–3 the use of special modes allowed to increase amplitudes of images compared to the NRZ mode: RZ mode: the second Nyquist zone — by 8.11 dBm, the third Nyquist zone — by 8.21 dBm,
