#overlapadd #overlapsave #sectionedconvolution

the response of an LTI system for any arbitrary input is given by linear convolution of the input and the impulse response of the system. If one of the sequence is very much larger that the other, then it is very difficult to compute the linear convolution using DFT for that the entire sequence should be available before convolution can be carried out and large amount of memory is required to store the sequences. this serious problems can be overcome by making use of sectioned convolution. In this technique, longer sequence is cut into the size of the shorter sequence. then the linear convolution of each section of longer sequence and the smaller sequence is performed. the output sequence obtained from the convolutions of all the sections are combined to get the overall output sequence. Two classifications in this method, one being overlap-add and the other being overlap-save method.

Hii sir.. Do you remember me I met you at the JNTUK.. Anyway thank you sir for your explanation

[aayushanand]

Sir Y2(n)
in overlap save method will be -8 not +8

[Anjanamadugula]

Ma clg lo mi lanti sir's nduku undaro teledhu una vallu nduku cheparo ardham kadhu thanks 😁 for detail explanation

[Vamshi_krishna]

It's very lengthy. Try to complete fast and easily method.

[manidhanush]

Sir y can't u come to our please come to our clg sir....

[engkutaiba]

thank you sir but, how can we find the value of L

[joshnasree]

In overlap save method what is the purpose of taking x3 value we can windup upto taking of x1, x values naaa

[vinaykumarkomakula]

Me lanti sir ma clg lo vundi vunte
Ma clg bagupadedhi.... Memu kuda bagu padevallam
