    Currents on a three phase system

    Hi everyone, is it possible to sum at any given moment in time L1 + L2 + L3, algebrically speaking? If so, what would this value represent? Thanks

    Signal spreading in spread spectrum technology (DSSS)

    Hi, I've been trying to understand DSSS, but I'm not an engineer and have trouble with one point. I get the fact that multiplying the user signal with the chip sequence is what spreads the signal. My question is, why is this? If the data rate is, say, 1 bps, and the chip sequence 1000 bits...

    Intensity and frequency of radio waves

    Hi, I am not a physicists and have been trying to understand some basic concepts about electromagnetic waves in the context of telecommunications. Now, this is what I know so far: the energy of electromagnetic waves is proportional to it's frequency (E = h*f), and basically it's the energy...
