Z-Domain Bode Plotting Function.

Parameters:¶

f : function¶

The Input Function, must be callable function object. Must be specified as transfer function of type: - S-Domain (when approx=False, default) - Z-Domain (when approx=True)

dt : float, optional¶

The time-step used, default=0.01

NN : int, optional¶

The Interval over which to be generated, default=1000

mn : float, optional¶

The minimum phi value to be generated, default=0

mx : float, optional¶

The maximum phi value to be generated, default=2*pi

approx : bool, optional, callable¶

Control argument to specify whether input funciton should be treated as Z-Domain function or approximated Z-Domain function. default=False

title : string, optional¶

Additional string to be added to plot titles; default=””.

xlim : list of float, optional¶

Limit in x-axis for graph plot. Accepts tuple of: (xmin, xmax). Default is False.

ylim : list of float, optional¶

Limit in y-axis for graph plot. Accepts tuple of: (ymin, ymax). Default is False.

sv : bool, optional¶

Save the plots as PNG files. Default is False.

disp3db : bool, optional¶

Control argument to enable the display of the 3dB line, default=False.

lowcut : float, optional¶

An additional marking line that can be plotted, default=None

magnitude : bool, optional¶

Control argument to enable plotting of magnitude, default=True

angle : bool, optional¶

Control argument to enable plotting of angle, default=True
