MATLAB: Chirp with gaussian envelope

communication

hi all, I need to use an up chirp pulse but with Gaussian envelope. Any idea that can help me?

t = -1:0.01:1;
env = normpdf(t);
x = chirp(t);
y = env.*x;

You did not specify the width of the pulse. I've made it 10 microseconds.

t = 0 : 1/1e6 : .01;         
d = 0 : 1/50e3 : .01;           
y = pulstran(t,d,@rectpuls,1e-5);
plot(t,y); 
axis([0 0.001 0 1.5])

Please replace the following line of code:

   periodogram(y, rectwin(length(y)), [], fs, 'oneside', 'power');

with:

   periodogram(y, rectwin(length(y)), [], fs, 'oneside', 'psd');
