Abstract: A system for converting a digital signal to an analog signal, the digital signal having a center frequency, includes: a multi-Nyquist DAC; a clock; and a controller configured to: control the clock to generate a clock signal such that the center frequency of the digital signal is an integer multiple of half the frequency of the clock signal, the clock being configured to supply the clock signal to the multi-Nyquist DAC and to the controller; and supply the digital signal to the multi-Nyquist DAC to generate an output signal.
