Abstract
In accordance with embodiments of the present disclosure, a method and apparatus includes an input having a first input terminal and a second input terminal for receiving an input waveform. In one example, the apparatus includes a capacitor having a first capacitor terminal and a second capacitor terminal, wherein the first capacitor terminal is coupled to the first input terminal, and at least one light-emitting diode coupled in series with the capacitor between the second capacitor terminal and the second input terminal, such that the light-emitting diode generates light in conformity with at least one of an amplitude modulation and a frequency modulation of the input waveform.
