By means of the DFT and IDFT, determine the response of the FIR filter with impulse response h(n)={1,2,3} to the input sequence x(n)={1,2,2,1}?
What is the sequence y(n) that results from the use of four point DFTs if the impulse response is h(n)={1,2,3} and the input sequence x(n)={1,2,2,1}?

In Overlap save method of long sequence filtering, how many zeros are appended to the impulse response of the FIR filter?
The first M-1 values of the output sequence in every step of Overlap save method of filtering of long sequence are discarded.
In Overlap add method, what is the length of the input data block?
Which of the following is true in case of Overlap add method?
What is the value of x(n)*h(n), 0≤n≤11 for the sequences x(n)={1,2,0,-3,4,2,-1,1,-2,3,2,1,-3} and h(n)={1,1,1} if we perform using overlap add fast convolution technique?
