Hi, In FDM, the total frequency bandwidth is split into small frequencies ranges for each user and send simultaneously after multiplexing. In TDM, I was wondering is the whole bandwidth given for a small time for each user while multiplexing And in fiber-optics, why is FDM not used...

Thankss.. So, aren't there are generators made based on wattage??.. or can we ignore the apparent power and use a generator to supply for the real power only? And also when the current returns to distribution point.. different cables with be with different power factors.. so will there be any...

In AC circuits, it seems that there is no energy used for capacitors and inductors. I was wondering how is the energy used causing it to increase and decrease the power factor?. And also, why does the power provider have to supply power(apparent power) for something that is ultimately not...

And also, does the capacitor charge up completely and discharge completely in each cycle of AC irrelevant of the capacitance and the frequency of the AC signal..?? Thanks.

I have some confusions regarding rectifier circuits. I was wondering does any change happen to the rectified dc voltage if i change the load resistance. I was thinking even if the current change with the change in resistance, there should not be any change in the voltage. But, it seems it is...

Hi, I have a very basic question. When a current carrying rectangular loop of wire is kept parallel to a magnetic field there is a torque in the loop of wire causing it to rotate. I was wondering what causes it to rotate further when the rectangular loop of wire is perpendicular to the...

Can someone explain to me if we can make the digital mux output all the inputted data as in a communication mux

Appreciate if anyone could clarify the digital mux part.

So, if we send low bandwidth channel by channel at a very fast rate, then we don't even need a high bandwidth channel. Just can send channel by channel using a low bandwidth channel

Thanks.. So what causes the rotor to rotate in the generator if no current is connected to the stator

Hi, I have a question regarding digital multiplexers. In communication systems, when we use mux, we can combine a lot of low bandwidth channels and transmit as a high bandwidth channel and then use a demux at the receiving end to split it back to the low bandwidth channels. I saw the...

Hi, I was having some confusion understanding how the three phase generator works. As far as I know AC is connected to the stator and DC is connected to the rotor and the changing magnetic field in the stator causes the rotor to rotate. I was wondering what causes the rotor to rotate in...
