With the time-lag correlation method, the bandwidth of the
|
|
|
|
power spectrum is determined by the maximum time lag (L)
|
|
used in the calculation:
|
|
|
Df = 1 cycle/(2LDt).
|
|
|
q |
Number of frequency band = (Nyquist frequency – 0) / Df
|
|
|
= (2 Dt)-1 / (2L Dt)-1
= L
|
|
|
q |
Number of degrees of freedom = N/(number of bands)
|
|
|
= N/L
