dsP2, a tiny Library in FlexC

At the moment I'm dealing with integral transformations, the CORDIC is excellently suited for this. A few examples and test results are in the appendix.

    Thanks! I'll be checking back here if I need a Hilbert transform for my SSB transmitter.

    Using a Hilbert transform to generate a single side band signal is somewhat more computationally efficient than the Weaver method. The Weaver method uses 2 low pass filters to reject the unwanted sideband. The Hilbert filter accomplishes the same thing with one filter and a simple time delay for the other data path. In addition, the Hilbert filter has every other filter coefficient as zero, so that makes computation faster.
