Hi GM,
>> HT -> Atan2 -> differenciate -> unwrap
Could you please explain how to find the drift using HT,
HT -> gives real(I) & imaginary (Q) components of real signal
Atan2 -> the phase of an I Q signal
diff-> gives what ?
unwrap ?

Actually, there are SRC chips available from Texas Instruments, just take look
at their website. They don’t cost too much and are found in countless digital
mixing consoles.
Best,

diff gives you the phase step per sample,
basically the frequency.
However the phase will jump back to zero periodically when the phase
exceeds 360°
(when it wraps around) in this case diff will get you a wrong result.
So you need to "unwrap" the phase or the phase difference, for example:
