plots of the phase-delay oscillator's outputs.

In order to get going, the analysis includes the `UIC` directive which asks to forgo the typical operating point calculation, and instead use the supplied initial values (see `.ic` line). The specific initial values used should be non-zero, it is simplest to set the battery terminal node (n0) to some non-zero value.

A plot of time-varying voltage at the output of phase delay oscillator as simulated by the Xyce circuit simulator. Oscillations start at around 250 milliseconds, and continue until the end of the plot at 2 seconds. The waveform at the transistors emitter rides at a DC offset of 4.5 volts. The waveform at the filter output is centered at 0 volts.Several cycles of the time domain output of the phase-delay oscillator. There are roughly 6 oscillations in 5 milliseconds which yields a frequency of roughly 1200 Hertz. The output of the low pass filter has a peak to peak voltage of 0.09 Volts and a small amount of harmonic distortion is evident in both the transistor's collector.
