well, i tried it with a phasor, but still got the same results.  the
really low frequencies (such as .001 Hz) tend to stretch the period
out.  i might try it with linseg instead of phasor since i can have
better control over the period.
i would love to know why this happens, and if the code could be fixed to
accomodate very low freqs.

:P
