meanfreq
Mean frequency
Syntax
Description
specifies the frequency interval over which to compute the mean frequency. This
syntax can include any combination of input arguments from previous syntaxes, as
long as the second input argument is either freq
= meanfreq(___,freqrange
)fs
or
f
. If the second input is passed as empty, normalized
frequency will be assumed. The default value for freqrange
is the entire bandwidth of the input signal.
meanfreq(___)
with no output
arguments plots the PSD or power spectrum and annotates the mean frequency.
