sg_cissoid
now anything about SALP TOOLBOX?
this is the code of the signal :
[y, t] = sg_cissoid(beta, f, Dim, <OSF>, <SNR>)
%
% Parameters: - beta : Vector with complex amplitudes
% - f : Vector with frequency values (-0.5 < f < 0.5)
% - Dim : Number of samples
% - OSF : Oversampling factor (default: OSF = 1)
% - SNR : Signal to Noise ratio in [dB] (default: SNR = inf)
%
% Output: - y : Vector with signal samples
% - t : Time axis
and this is the code of welch for example :
[PSD, f] = psd_welch(y, <Win>, <N_Overlap>, <N_FFT>, <fs>)
%
% Parameters: - y : Vector with signal samples
% - Win : The signal is divided into K_seg overlapping
% segments of length equal to the length of
% the window and windows each segment
% (default: 8 segments with Hamming window)
% - N_Overlap : Number of overlapping samples from segment to
% segment (default: 50% overlap)
% - N_FFT : Number of FFT points (default: N_FFT = 256)
% - fs : Sampling frequency in Hz (default: fs = 1 Hz)
%
% Output: - PSD : Power spectral density
% - f : Frequency axis
anyone can tell me...which parameters should i change to see the resolution ???
