Sinc plot using Matlab

sinc function in matlab

Hi,

Can anyone tell me how to plot this fn using matlab


Tb sinc^2(fTb)sin^2(pi.f.Tb)

matlab sinc

If you have the DSP toolbox then you can use the sinc() function but otherwise you will have to write to explicitly create the sinc with sin(x)./x.

%Create a time vector 
t = 1 : .1 : 10 ;

%Create signal
y =  Tb*sinc(f*Tb)^2*sin2(pi*f*Tb)^2 ;

%Plot
plot(t,y)

You'll need to define Tb and f also.
