4.1.4 PWLWave
Command structure of PWLWave.
PWLWave returns a numerical value in case the first argument is numeric, otherwise a CheckedPWLWave is returned. If the last argument is not specified PWLWave returns an interpolating function object. CheckedPWLWave is a data type which marks a PWLWave description as being syntactically correct. CheckedPWLWave should not be defined directly.
A CheckedPWLWave can be displayed with standard Mathematica graphic functions such as Plot or with Analog Insydes graphic functions such as TransientPlot.
PWLWave has the following optional arguments:
Arguments of PWLWave.
Examples
Load Analog Insydes.
In[1]:= <<AnalogInsydes`
Select data pairs.
In[2]:= data = {{0.1, 0}, {0.5, 0}, {1, 1}, {1.5, 1},
{2, 0.5}, {2.5, 0.5}, {3, 0}};
Define piecewise linear source.
In[3]:= Vpwl1[t_] = PWLWave[t, data]
Out[3]= 
Define repeated piecewise linear source.
In[4]:= Vpwl2[t_] = PWLWave[t, data, 0.5, 1]
Out[4]= 
Display the signals.
In[5]:= TransientPlot[{Vpwl1[t], Vpwl2[t]}, {t, -1, 7}]
Out[5]=
