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 signalinputin the frequency range betweenfminandfmax. Specifyfminandfmax在相同的频率单位sinestream迹象al.

input2 = fselect(input,index)extracts a sinestream signal at specific frequencies, specified by the vector of indicesindex.

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)
