10 Virtual Analog Oscillators
Virtual Analog (VA) oscillators are interestingly named. They have nothing to do with analog circuits, components, block diagrams, or signal flow. They do not model the physical characteristics of any kind of analog oscillatory system, like pendulums or springs with attached masses. Analog oscillators have no Nyquist limit and cannot alias. Their waveform shapes look identical to those of trivial oscillators, no matter what the frequency of oscillation. One of the goals for VA oscillators is to preserve that perfect shape as much as possible. The applications of VA oscillators tend to take two directions. One is to retain the perfect analog oscillator waveform and harmonic spectrum with either no aliasing or ...
