Deterministic signals
Stationary, deterministic signals are
made up entirely of sine waves at
discrete frequencies. The resolution
of the frequency analysis is determined by the filter bandwidth used
in the analysis. The filter bandwidth
should enable the analyzer to distinguish between the two most closely
spaced frequency components. This
means that there should only be one
sinusoid in each filter passband at
any one time. If this is the case, then
the power transmitted by the filter is
independent of the bandwidth.
Therefore, the averaged frequency
spectrum of a deterministic signal
should be scaled in terms of root
mean square (RMS) or mean square,
power (PWR).
