Example on Time shifting

[@arpitsrivastav9609]

You have done a good job, Very easily you have explained it. Very well Done buddy Keep up the good work and Keep Educating people. Best Wishes

Thank You Arpit , Happy Learning:-)

function in MATLAB that will take a sequence x[n], and shift it to the left or to the right by a given number of samples. use the function written to find the sum of the results obtained by shifting x[n] to the right by 2 samples and and obtained by shifting x[n] to the left by 2 samples. kindly provide the codes🙏

Sir If I have the signal like y(n)=x(n-5)-x(n+2) what will be the code

[@gambu4810]

Hi knowledge. Thank you for the informative video. Can you show how to make an animation of a time shift?

[@KnowledgeAmplifier1]

Sure , I will make one video on this topic , Stay tuned :-)

Bro I want to do shifting by getting input from user

How to add the original and the shifted signal

[@KnowledgeAmplifier1]

Check this video please-->Signal addition in MATALB
ruclips.net/video/cHb8Gsk2fFQ/видео.html
Now if you have the original signal and shifted one , you can add simply :-)
For example , in the above case , if you want to add , the code will be like this-->
n1=0:4;
x=[0 1 2 3 3];
n2=n1-2;
y=x;
u=min(min(n1),min(n2));
t=max(max(n1),max(n2));
r=u:1:t;
z1=[];
temp=1;
for i=1:length(r)
if(r(i)max(n1))
z1=[z1 0];
else
z1=[z1 x(temp)];
temp=temp+1;
end
end
z2=[];
temp=1;
for i=1:length(r)
if(r(i)max(n2))
z2=[z2 0];
else
z2=[z2 y(temp)];
temp=temp+1;
end
end
z=z1+z2;
subplot(3,1,1);
stem(r,z1);
subplot(3,1,2);
stem(r,z2);
subplot(3,1,3);
stem(r,z);

Just can u just tell me the code for
U(n)+u(n-1) .

@@KnowledgeAmplifier1 thanks 😁

[@ninaddevdas6953]

sorry to say but it is wrong N+2 means advancing the signal which means the signal should move to the opposite side as shown in your video

[@KnowledgeAmplifier1]

I have explained in the video as N+2 but later I have shown the reverse case too , so for that I have used n-2 , watch the whole video please and then comment :-)

[@ninaddevdas6953]

N-2 means delaying the signal in which the signal should move towards the positive axis But it is opposite in your video

[@ninaddevdas6953]

you can take Signal and System by nagoor kani as reference

[@KnowledgeAmplifier1]

@@ninaddevdas6953 please watch the figure at 3:56 , I have done that ony , N-2 means delaying the signal , which means signal should move towards the positive axis , to timplement that in MATLAB , you have to write m=n+2

[@KnowledgeAmplifier1]

@@ninaddevdas6953 ya , you check the figure at 3:56 and verify whether it is correct or not

[@abdullahehsan5311]

n-2 means advance and n+2 means delay..

[@KnowledgeAmplifier1]

No the reverse one correct , check the theory properly

Don't get confused :-)

[@abdullahehsan5311]

It is wrong

[@KnowledgeAmplifier1]

No for sure , it's correct :-)
