I am searching for calculating the maximal frequency existing in some discrete signal. Here are the values of the signal: 1.0e+003 * 2.3784 2.3435 2.3145 2.2680 2.2785 2.2380 2.1580 2.1234 2.1168 2.1215 2.

And after having calculate this frequency, I will apply wavelet so theis frequency is devided by 2 at each level. Can someone give me the relation between this frequency and the cutoff frequency of the wavelet filter ?
