Max V of Digital Signals

Depends how near you are to the transmitter.

If current signal is converted into digital signal at transmitting end ,can we get at the same current signal at the receiving end (similar to voice or video signals with little distortions).

If yes ,why are the wireless communication /broad band not used for current transmission and distribution ???

1) Yes.

2) Because you can only recover the original current or voltage level by amplifying the output of the digital to analogue converter in the receiver (which obviously needs a local power supply).

Thanks..

1. But if wireless transmission is used we can prevent the transmission and distribution losses which accounts for 26% of the power generated ..

2. Will the local power required to reconstruct the signal be less than power losses.

When an analogue signal is sent via wireless the POWER received is in the microwatt region.

To expand on my last post (which I send from my phone in haste):

"Will the local power required to reconstruct the signal be less than power losses ..."

The local power required to reconstruct the signal will be far greater than any power transmitted.

There have been ideas suggested about wireless power transmission - it is practical (over a very short distance) using inductive loop coupling - which is more-or-less like taking the primary and secondary coils of a transformer, and using an air gap between them (across which the power is transmitted). Other similar short-range methods are being developed. All the schemes I know of have losses far greater than 26%.

For longer range energy transmission, you could research the work of Nikola Tesla - who was some kind of genius, but just didn't get it right (and no-one else has since).

You have two choices:

1) Spend a considerable time (maybe the rest of your life) trying to do this (which, by the way, goes against the "laws of physics" as we know them) - with very little certainty of success.

2) Move on - find something more practical.

Good luck.
