intdec
Changes sampling rate of a signal
Syntax
[y]=intdec(x,lom)
Arguments
- x
input sampled signal
- lom
For a 1D signal this is a scalar which gives the rate change. For a 2D signal this is a 2-Vector of sampling rate changes
lom=(col rate change,row rate change)- y
Output sampled signal
Description
Changes the sampling rate of a 1D or 2D signal by the rates in lom
Examples
Fs1 = 1000; // initial sampling frequency Fs2 = 1400; // targeted resampling frequency t1 = linspace(0, 5-1/Fs1, Fs1*5)'; t2 = linspace(0, 5-1/Fs2, Fs2*5)'; F0 = 2; // Signal frequency u1 = sin(2*%pi*F0*t1); u2 = sin(2*%pi*F0*t2); // Direct sampling at targeted frequency (as reference) u2b = intdec(u1, Fs2/Fs1); // Resampled signal clf plot(t2,u2,"b", t2,(u2b-u2)*1e13, "m"); legend("Direct highly sampled u2","Resampling_error x 1e13","in_upper_left");
