Modulation circuit for a light emitting device
TLDR
In this article, a modulation circuit is designed to provide an LED with a more analog type signal, which in turn causes the LED to emit a signal that is peaked rather than a constant square wave providing a better conversion frequency to the fundamental frequency.Abstract:
