3.9 Graphics Functions
Analog Insydes extends Mathematica’s graphics functionality by several custom functions for producing
frequently used graphs in circuit design. The package provides special functionality for displaying
the following types of plots:
BodePlot (Section 3.9.1)
FourierPlot (Section 3.9.2)
NicholPlot (Section 3.9.3)
NyquistPlot (Section 3.9.4)
RootLocusPlot (Section 3.9.5)
TransientPlot (Section 3.9.6)
Bode plot (frequency response: magnitude and phase vs.
frequency)
Fourier spectrum plot (frequency spectrum: spectral
magnitude vs. frequency)
Nichol plot (frequency response: gain vs. phase)
Nyquist plot (frequency response: imaginary vs. real part)
pole/zero and root locus plot (parameter response:
imaginary vs. real part)
transient waveform plot (signal value vs. time)
3.9.1 BodePlot
BodePlot[func, {var, f
, f
}]
displays a Bode plot of the transfer function func[var] as
the independent variable var is swept from f
to f
BodePlot[{func
, func
, † † † }, {var, f
, f
}]
displays the transfer functions func
, func
, † † †
simultaneously in a Bode plot
Command structure of BodePlot.
BodePlot displays one or several transfer functions in a Bode plot. A Bode plot consists of two
separate charts in which the magnitude and phase of a transfer function are plotted vs. frequency.
Magnitude and phase are displayed, respectively, on logarithmic and linear scales. The frequency
axis is scaled logarithmically for both charts.
Note that BodePlot has attribute HoldFirst.
BodePlot supports additional patterns for displaying numerical data generated with the functions
ACAnalysis (Section 3.7.3), NoiseAnalysis (Section 3.7.4), or ReadSimulationData (Section 3.10.3):
