Thankyou very much sir. You explained it really in a very easy way. 🙏🏻. Saved me from my lecturer 🙏🏻🙏🏻🙏🏻 .

[aditiparetkar]

thank you sir for your efforts, very well explained!

Sir, can you please post and explain code for convolution of two discrete time signals

[haidisaid]

Is this addition of two discrete time signals or two digital signals?

[VarshaSingh-jdql]

can you let me know a bit how to do via functions ?
I tried like this but error:
function [y, r] = seqadd (n1, n2)
u=min(min(n1), min(n2));
t=max(max(n1), max(n2));
r=u:1:t;
temp=1;
y1 = [];
for i=1:length(r)
if(r(i)<min(n1) || r(i)>max(n1))
y1=[y1 0];
else
y1=[y1 x(temp)];
temp=temp+1;
end
end
y2 = [];
temp=1;
for i=1:length(r)
if(r(i)<min(n2) || r(i)>max(n2))
y2=[y2 0];
else
y2=[y2 y(temp)];
temp=temp+1;
end
y=y1+y2;
end

Thank you so much for this, you saved my life <3

Hi sir ty for the video, i've a question, how can we do it with multiplication, what changes we make?

[subratkumarpanda]

Can u pls provide the code for a sampling signal

[jatingoyal]

thanks .. can u pls provide code for this signal
Find convolution between x1[n] = (0.5^(n-2) u [n-2] )and
X2 [n] = u [n+2] .

[rahulmeena]

Can u plz explain how z1=[z1 x(temp)] are equal??

[gokulmukil]

can you give signal multiplication and division code

[rahulmeena]

It shows error x(temp) undefined x and y

[HarisKhan]

Hi
Can u explain how to add continous signals having different time range?
