ABSTRACT:
A modulation circuit for controlling a light emission device to produce an intensity-modulated light signal based on an input modulation signal. The modulation circuit includes a level detector and an attenuator. The level detector produces an electrical signal corresponding to an amplitude level of the input modulation signal. The attenuator attenuates the input modulation signal based on the electrical signal, and applies the attenuated input modulation signal to said light emission device.
