Discrete synthesis using staggered Nyquist regions avoids guard band induced holes near a Nyquist limit

Staggered consecutive Nyquist regions associated with differing DAC synthesizer clock rates (FCLK) avoids spectrum lost through disjoint guard bands at the end of or between adjacent Nyquist regions. The staggered consecutive Nyquist regions overlap by an amount at least as much as is consumed by the guard bands. Selectable reconstruction filters associated with each Nyquist region and its DAC clock rate are used to enforce the staggered Nyquist regions and their various guard bands.
