Hello
I am estimating the Instantaneous Frequency using the following code and it works well.
h=hilbert(acc);
unrolled_phase = unwrap(angle(h));
inst_freq = ((diff(unrolled_phase))'./diff(T))/(2*pi);
I want to estimate the arrival time of each frequency and Can someone help me do that?
Thanks
Jetson

I am not sure what you mean by arrival time, but you can convert phase to time by multiplying by frequency.
