The DSP core of PowerSDR is DttSP (<http://dttsp.org>) by N4HY and me. The
DSP functions in QS1R and uWSDR are closely derived from it. Any sample rate
limitation is imposed by hardware and associated OS software, not by the DSP
code.

If you can get samples in and out fast enough, and you have enough CPU
cycles to keep up with the arithmetic, the DSP will run at whatever speed
you tell it, in the form of a single number (the sample rate) provided at
initialization.
