The use of LEDs for illumination and simultaneous communication becomes more and more interesting and it goes hand in hand with the increasing deployment of LEDs to peoples homes and industrial buildings. Modulation of this kind of light sources is difficult because of high voltage and of current demands. Since the LED configurations and the values of current and voltage are different, the universal modulator suggested by the research team of the Department of Telecommunications should be abledoi:10.15598/aeee.v12i1.845 fatcat:l556jnr2znbqxfvpmf5qwb5mzu
