Hi,

I have a sinusodal signals with fixed frequencies(multi-tone).
But the signal is randomly on and off.
What I did is that once the signal is off, I discarded the portion and
then, when the signal is on, I attached the signal afterward.
So, now, the signal becomes phase discontinued, same frequency,though.

My frequency tracking algorithm works with the original sinusoida
signals(without off). Not it cannot track the phase-discontinued signa
properly.
Is there any way to track the frequency of the signal?

Thank you in advance.
