How to Recover The Clock Symbol of received 2 FSK Signal

[sangoogle]

Hello Engineers,

Contribution from the experienced Engineers are greatly appreciated.

I need to recover the symbol clock from 2 FSK.

The following attachment shows two responses, the second one represents Freq vs Time from which I need to recover the symbol clock, so that I can clock once on each bit.

Please let me know for a regular data (ex : 101010) & random data.

Thanks in advance.

Hi sangoogle,

In the case of synchronous transmission, standard methods for clock recovery can be used, for example the early-late gate.
That methods work fine for random data.

Hi Zerro,

Thanks for your valuable information, I'll try with early late gate method.......
