In this paper a prototype of a free-space optical communication system is proposed. The transmitter is equipped with a blue 1W LED and a low-cost microcontroller implementing a digital modulation scheme. The receiver converts the incoming light into a current through a photodiode and another identical microcontroller is employed to demodulate...

In this paper a nonlinear model is proposed to characterize ferrite-core inductors operating in saturation region in Switch-Mode Power Supplies (SMPSs). The model, identified through experimental measurements of inductor current and voltage, relates the inductance to the current flowing through the inductor and also to the SMPS load current....
