yes! dan!
i can hear only tunes of 1's and 0's but they can't be shown on fft! in matlab. and i think code is 100% right!
if you want to know about code then i can show you??
and furthermore in my university none of other have work on pzt still.
so how much it would be cost in pakistan...
thank you Dan,
yes , Dan : i tried at frequencies about 10s Khz, but as usual i am receiving same sort of different signal but still can't distinguish b/w 0's and 1's. and distance b/w rx(hydrophone) and tx(projector) is very very small let say about half of the (half of meter)
no i have...
thank you dear! for your response.....
no i am not using any pre-amp circuit..
my frequency of operation for 1's is 1000hz and for 0's 500hz i am using fsk modulation..
and further more my tup is about 1 meter (just for analysing)
and yes there is some sort of signal coming but it is totally...
hi! i am trying to make 'pc-based underwater acoustic communication system" in which i have two laptops.
laptop 1 is connected to acoustic projector(device that converts electrical pulse into sound wave)
while...
laptop 2 is connected to acoustic hydrophone(device that converts sound wave...
Re: i have a problem while transmiting the signal which is fsk modulated!
thank you very much! BradtheRad! i tried on the diffrent computer and i got my result ! thank you very much
Re: i have a problem while transmiting the signal which is fsk modulated!
yeah! i was just trying since last 3 days!
i also change their frequencies (carrier's and base band signal) but the result was same as i had shown you before!
i also tried to transmit diffrent binary code! let say...
Re: i have a problem while transmiting the signal which is fsk modulated!
Yes, this alternating 1's and o's comes at transmitting side but not at receiving side! that is exactly my problem!
Please suggest what should i do for this!
is there any snyc problem?? how to do sync?

Re: i have a problem while transmiting the signal which is fsk modulated!
you are right but i have to do only fsk not the AM. and for the sync, if you see my code, i have done. b/c for receiving side i have set duration about 4 seconds and for the transmitting side i also set 4 seconds of...
Re: i have a problem while transmiting the signal which is fsk modulated!
yes you are right! basically i tried to transmit bit by bit and the received signal is in the image shown!
and if you know that whether i have received it or not guide me further!
**broken link removed**
hello ! can any one help me!!
i want to transmit fsk modulated signal from one pc to another pc through their sound cards! and these pc's are connected to each other via cord cable! the problem is i couldn't understand whether the signal is received or not? plz if any one knows guide me!
code...
