for inverse of twiddle matrix we have to also take transpose after taking the conjugate of the matrix

Find circular convolution of sin (nπ/2) for n=0,1,2,3 where h(n)=2n where n=0,1,2,3 using DFT AMD IDFT METHOD

[@neha6165]

Sir am not able to find a video based on linear convolution using DFT of the given sequences x(n) and h(n) sir will uh pls mention the link sir ?

find circular convolution of x(n) = (3,5,1,2) h(n) = (7,1,8,2) ?

I want classes of adsp is that available??

Sir dft lo j,-1,1 avi ala vesaru Sir

[@gauravkulmethe3628]

Sir since we are multiplying two matrix X1 and X2 why you haven't done multiplication using multiplication operation of matrix which elements of row multiplied by elements of column.

[@gauravkulmethe3628]

You have done multiplication through element to element multiplication..

[@ECAcademy]

Follow the procedure as shown....

@@gauravkulmethe3628 exactly, same doubt sir .. we'll get (4*4) matrix after multiplication

[@souravpramanik2252]

@@purveeraj2174 I think ,this may be a dot product thats why

[@ArunKumar-jg8gx]

Sir has not mentioned but that is a short cut method..... solution is completely corr the 😊

[@siddhikadam7982]

Sir is it time domain or frequency domain?

[@ECAcademy]

Frequency domain…

should not we first check the length of output linear convolution and circular convolution

Sir ,in previous video ,you find circular convolution of same sequence i.e {16,14,16,14}
in this video ,u also find Circular Convolution (using DFT) ,but both ans is not matched ,i can't understand that , can u please help me ?

[@pheonix1621]

Bhai puri video dekh bhai dft ke baad Yk aya hai uska jab IDFT karega to yn aayega usse bolte hai convolution of xn1 and xn2

[@souravpramanik2252]

@@pheonix1621 I think u r right bro

[@semiconductor9149]

Ans of Circular convolution should be same na
Either using DFT or IDFT??

[@manasgupta349]

no, first you perform DFT to find X1(k) and X2(k) and then you perform IDFT to obtain final result
