fselect
Extract sinestream signal at specified frequencies
Syntax
input2 = fselect(input,fmin,fmax)
input2 = fselect(input,index)
Description
input2 = fselect(input,fmin,fmax)
extracts
a portion of the sinestream input signal input
in
the frequency range between fmin
and fmax
.
Specify fmin
and fmax
in the
same frequency units as the sinestream signal.
input2 = fselect(input,index)
extracts
a sinestream signal at specific frequencies, specified by the vector
of indices index
.
Examples
Extract the second frequency in a sinestream signal:
% Create the input signal input = frest.Sinestream('Frequency',[1 2.5 5],... 'Amplitude',[1 2 1.5],... 'NumPeriods',[4 6 12],... 'RampPeriods',[0 2 6]); % Extract a sinestream signal for the second frequency input2 = fselect(input,2) % Plot the extracted input signal plot(input2)
