Description: Energy and Power Spectra
It is frequently useful to study the distribution and power of a signal in the
frequency domain. For example, we may wish to have estimates for how the
power in a signal is distributed with frequency, so that we can quantitatively
state how much power is in a particular band of interest relative to other fre-
quencies. Given a power spectral density function, the power is then given by
the integral of the function over the band of interest. Platform: |
