hi all;
a signal is described as following:
- has 6000 samples
- sampling frequency is 10000 Hz
- the signal consists of 15 tone bursts (each tone has a unique frequency
from 0 - 5000 Hz
- duration of each tone burst is 15 - 20 ms (150 - 200 samples).
- the signal is contaminated by noise.
i need to write a MATLAB program to detect the frequencies of the 15 tone
bursts. anyone can help?

thanks
