Editing Bode plot (section)

===Corrected amplitude plot===

To correct a straight-line amplitude plot:
* At every zero, put a point <math>3 a_n\ \text{dB}</math> '''above''' the line.
* At every pole, put a point <math>3 b_n\ \text{dB}</math> '''below''' the line.
* Draw a smooth curve through those points using the straight lines as asymptotes (lines which the curve approaches).

Note that this correction method does not incorporate how to handle complex values of <math>x_n</math> or <math>y_n</math>. In the case of an irreducible polynomial, the best way to correct the plot is to actually calculate the magnitude of the transfer function at the pole or zero corresponding to the irreducible polynomial, and put that dot over or under the line at that pole or zero.
