Hello students, using the given definition, the fibonacci sequence for n equal to 0 to 9 is as follows h of 0 equal to 0, h of 1 equal to 1, h of 2 equal to h of 1 plus h of 0 is equal to 1, h of 3 equal to h of 2 plus h of 1 that is equal to 1 plus 1 equal to 2, h of 4 equal to h of 3 plus h of 2 this is equal to 2 plus 1 equal to 3, h of 5 equal to h of 4 plus h of 3, h of 3 that is equal to 3 plus 2 equal to 5, h of 6 equal to h of 5 plus h of 4 this is equal to 5 plus 3 equal to 8, h of 7 equal to h of 6 plus h of 5 this is equal to 8 plus 5 equal to 13, h of 8 equal to h of 7 plus h of 6 this is equal to 13 plus 8 equal to 21 and h of 9 equal to h of 8 plus h of 7 equal to 21 plus 13 that is equal to 34.
02:04
So, the fibonacci sequence, so the fibonacci sequence, fibonacci sequence for n equal to 0 to 9 is 0 1 1 2 3 5 8 13 21 and 34.

Now, we perform the steps for the four -point fft using the definition in matrix form.
02:41
First, we reduce modulo 4 given sequence is x equal to 0 1 1 2, reduce each element modulo 4 x mod 4 is equal to 0 1 1 2.
03:06
Now, the four -point dft matrix is f equal to 1 1 1 1 1 i minus 1 minus i 1 minus 1 1 minus 1 1 minus i minus 1 i, this is the four -point dft matrix.
03:54
Now, we compute the dft using matrix multiplication x equal to f x modulo 4.
04:05
So, the four -point the four -point idft matrix is the conjugate conjugate transpose of the dft matrix dft matrix...
