Re: transmitting clock signal

Hi john
Good idea, I was thinking about sending sine wave (carrier), and
convert it to square at the other end, but usually when you convert
sine to square, the converted square will not has the same sine
frequency, and alwayes it is not a true square
thanks

Hi all
Is there any simple way to send a clock signal (square waves), by
radio?, what is the maximum clock frequency that I can send and receive
by radio?
Thanks
how far?
how fast?
how much?


There is no point in asking questions; the OP clearly doesn't understand
anything.

You don't need to send square waves; if you did, WWV would send them!
You send sine waves, and square them up with a limiter at the receiving
end.

You just want to send, and receive, an accurate frequency. So you can't
use a superhet receiver if you use the carrier as the 'accurate
frequency'. But that gets you the highest possible sending frequency,
and current techniques will let you go beyond 100 GHz, which is likely
to be too fast for any clock you want.

The answer to 'how far' is 'to the boundaries of the Universe';

The answer to 'how fast' is 'around 300 000 km/s';

The answer to 'how much' is ' about 50% of what it costs to do a good
job, as usual'.
