I have a data pattern 11100100. And I want to generate matlab plots with 3 pulse shapes p(t), namely: square pulse, raised cosine pulse in time domain from 0 to T and raised cosine pulse in frequency domain from 0 to 6T by applying these pulse shaping filters on the binary data.
Any help is much appreciated.

Square Pulse:
data=[1 1 1 0 0 1 0 0];
stairs([data,data(end)],'r','linewidth',2);

next try by yourself

Hi Kalyan,
I want to apply the above pulse shaping filters on the binary data. That is, if my binary data is represented as a sequence of impulse signals, then i have to design a (square pulse, raised cosine pulse in time domain from 0 to T and raised cosine pulse in frequency domain from 0 to 6T) pulse shaping filter. Then multiply(perform convolution on) my input impulse signal with the filter to get the pulse shaped output.
So I would would request you to kindly help me with this one.
Thanks and Best,
Sai..

Is this one you are looking for?
data=[1 1 1 0 0 1 0 0]
subplot(311),stairs([data,data(end)],'r','linewidth',2);
title('Data');
filt=randi([0 1],1,length(data)) % Random Pulse filter Choosen
subplot(312),stairs([filt,filt(end)],'g','linewidth',2);
title('Pilse Shape filter')
result=data & filt
subplot(313),stairs([result,result(end)],'b','linewidth',2);
title('Filtered Data');
Requested you to try others by yourself.
