Step1: Perform Row-wise Transform using FFT Flowgraph

For row1 = [0, 1, 2, 1]

enter image description here

For row2 =row4= [1, 2, 3, 2]

enter image description here

For row3 = [2, 3, 4, 3]

enter image description here

Result of row-wise transform is,

$R=\begin{bmatrix}4&-2&0&-2 \\ 8&-2&0&-2 \\ 12&-2&0&-2 \\ 8&-2&0&-2\end{bmatrix}$

Step2: Perform Column-wise Transform using FFT Flowgraph

For column1 = …
