Modulation of phase, amplitude or polarization can all be ... a configuration known as the coupled optoelectronic oscillator. Researchers in a number of groups around the world have demonstrated ...

This oscillator not only provides quadrature outputs but also allows for arbitrary phase shift generation and amplitude modulation. The design is robust against variations in component tolerances ...

In our recent feature on tremolo, we described how a valve can be configured to create a low-frequency oscillator (LFO) that can modulate amplitude ... mélange of pitch modulation, tremolo ...
