Summary[edit]
| Description |
A signal and the magnitude of its analytic signal, to demonstrate the envelope effect. I made it using Octave (that uses Gnuplot internally to output in SVG). Here is the code:
t=[0:.0001:3];
y1=-(1.2./t)-t+3;
y1(y1<0)=0;
y2=sin(2*3*pi*t);
y3=y1.*y2;
hil=abs(hilbert(y3));
gset terminal svg enhanced fname "Times" fsize 20
gset output "analytic.svg"
gset nokey
gset yrange [-1:1]
plot(t,y3,"3",t,hil,"1");
