Changes sampling rate of a signal

Calling Sequence




input sampled signal


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)


Output sampled signal


Changes the sampling rate of a 1D or 2D signal by the rates in lom


Fs1 = 10000;
Fs2 = 14000;
t1 = 0:1/Fs1:10;
t2 = 0:1/Fs2:10;
F0 = 500;
u1 = sin(2*%pi*F0*t1);
u2 = sin(2*%pi*F0*t2);
u2b = intdec(u1, Fs2/Fs1)
plot(u2b, u2);
