If x(n) ={n for 0<=n<=10
0, otherwise
y(n)= x(n) * x(n)
then y(4)=?

• y(n)= x(n) * x(n)
  y(4)= x(4) * x(4)
  
  now, x(n) ={n for n belongs[0,10] so, x(4)= 4 as
  so, y(4)= 4*4 =16

• given is finite sample sequence starting from 0.
  total num of samples 11 including x(0)=0.
  so linear convolution is
  0000000000...
  0123456789...
  02468..............
  039.................
  048............
  y(n)={0,0,1,4,10,23,...............}
  ds seq start from 0 sample
  y(0)=0
  y(1)=0
  ............y(4)=10

• 16? that simple? Gate? or am i missing something?

• y(n)= x(n) * x(n)
  y(4)= x(4) * x(4)
  
  now, x(n) ={n for 0

• hey its 20 u can do it simple by using periodic convolution.
• 10 years agoHelpfull: Yes(0) No(0)
• sorry linear convolution not periodic
• 10 years agoHelpfull: Yes(0) No(1)
• guys it is convolution not multiplication
  I hope ans is 10 by linear convolution

• x(n)=n...here n=4..so x(4)=4
  y(n)=x(n)*x(n)
  y(4)=x(4)*x(4)=4*4=16
