Name:

    ac_generator - provides AC input current

Description:

      This device produce an ac-current which are sent by a CurrentEvent. The
      current is given by

      I(t) = offset + amplitude * sin ( om * t + phi )

      where

      om  = 2 * pi * frequency
      phi = phase / 180 * pi

      The parameters are

      amplitude   double	-  Amplitude of sine current in pA
      offset	 double	-  Constant amplitude offset in pA
      frequency   double	-  Frequency in Hz
      phase	 double	-  Phase of sine current (0-360 deg)

      Setting start and stop (see StimulatingDevice) only windows the current
      as defined above. It does not shift the time axis.

Sends:

    CurrentEvent
