         Notes
         -----
-        This method creates a frequency sweep where frequencies are logarithmically spaced
-        across the frequency range, with ``num_points_per_decade`` points per decade.
-        This is useful for frequency response analysis where you want equal resolution
-        in log space. It corresponds to .ac parameter in SPICE.
+        This method creates a logarithmically spaced frequency sweep.
+        It is analogous to the SPICE AC analysis command for a decade
+        sweep:  ``.ac dec <num_points_per_decade> <fmin> <fmax>``
