Fix the overflow errors thrown by np.tanh(x) warnings in various waveforms. The error is thrown (on windows) when the argument x is complex with a sufficiently large real component. However, the waveforms are only evaluated against time (a real number), so treating x as complex is unnecessary.
Changes:
Call x.real but return the results as a complex type for consistency (there is no restriction that the waveform returned cannot be complex).
